Depression and addiction often go hand in hand. Doctors call this dual diagnosis or co-occurring disorders. One study found that around 37% of people with alcoholism problems and 53% of people with drug abuse problems also have a mental health condition like depression or anxiety alongside it. That is not a coincidence. The two conditions feed off each other, making everything harder.
When you’re struggling with your mental health and abusing alcohol, dependent on prescription drugs or misusing illicit drugs to get through, you end up stuck in a pattern that feels impossible to break. But when both issues are addressed together, things really can start to change.
How depression and addiction interact
Depression is sometimes mistaken for just feeling really sad, but it is a far more oppressive condition. Depression can drain you so much that getting out of bed feels like a marathon, and things you used to enjoy start to feel completely pointless. It can leave you totally exhausted but unable to ever sleep properly, lying awake every night with your mind telling you that nothing will ever get better.
When you feel like that, it is completely understandable to try anything that takes the edge off. Alcohol and drugs can work quickly, and for a few hours, the weight lifts, and you may even feel something close to normal.
But this doesn’t last, and you end up feeling worse than before. That is partly down to brain chemistry. Alcohol is a depressant, and while it might numb things for a bit, drinking regularly drains the chemicals your brain needs to keep you feeling okay. The same is true for a lot of drugs, both illegal ones and prescription medications.
The guilt and shame can also make things a lot worse. As substances become more of a crutch to cope with depression, the rest of your life is affected. You wake up hating yourself for drinking again, or cancel plans because the drug comedown makes it impossible to leave the house. Your relationships and work suffer, and you end up isolated and feeling like you’ve lost control. That makes the depression worse, which makes you want to drink again or use more drugs. And round it goes.
The risks of self-medicating
Using alcohol or drugs to deal with how you’re feeling is called self-medicating. And as we said above, it makes complete sense why people do it. The problem is that the relief is short and the cost is high.
There are many health and personal risks that come with self-medicating, but if you are living with depression and addiction, one of the most serious is suicide. Around 40% of people getting help for a drinking problem have tried to take their own life at least once.
Both depression and heavy drinking make suicide more likely on their own, but together, they pose a huge danger. Being drunk makes you more impulsive and less able to see a way forward. Thoughts that you might resist sober become harder to fight off. Drug use causes similar issues.
This isn’t said to frighten you, but to spell out the risks of letting things continue as they are without getting help. If you’re drinking or using drugs heavily and feeling hopeless, you need proper support, not another night trying to get through it alone.
Signs of depression and addiction
Both depression and addiction mess with how you see things, and denial comes with the territory. Seeing through this denial isn’t easy, but there are warning signs to look for.
With depression, you may experience sleeping issues, like nighttime insomnia, or sleeping all day and still feeling shattered. You may lose all interest in relationships, work, hobbies, and education. You may feel worthless, or numb, or just empty. These feelings are more than just a couple of bad days and last for weeks or, in many cases, years.
With addiction, you may find you need to drink more or take more drugs to get the same effect, spend more time getting hold of the substance or recovering afterwards, or carry on even when it’s clearly hurting you.
Part of what makes this hard to spot is that the two blur into each other. You wake up feeling dreadful and assume it’s the hangover. But some of that is depression. You can’t face seeing anyone and think it’s because you’re ashamed of your drug use. But some of that is depression, too. The substance use hides the depression, and the depression gives you a reason to keep using substances. This tangle is what makes
Why treating only one condition rarely works
For a long time, addiction services and mental health services have worked separately. This means that historically, you would get sent to one or the other, not both. That’s starting to change, but it’s still common to fall through the gap.
The problem is obvious. Imagine you stop drinking but don’t get help for the depression. You’re now sober and still struggling with symptoms. The thing you used to rely on is gone, and nothing has replaced it. You want to drink again, and the unfortunate reality is that you probably will.
Or imagine you get put on antidepressants and start therapy, but keep drinking heavily. The medication can’t do its job properly, and the depression doesn’t get any better because the thing feeding it is still there.
But NHS Trusts that have started treating both problems together have seen patient suicide rates drop by 25%. Addiction treatment centres like UKAT have seen positive results when providing treatment which takes dual diagnoses into account. That is what happens when you stop pretending these are separate issues.
What integrated treatment looks like
Integrated treatment means getting help for substance dependence and mental health at the same time, from people who understand how the two connect.
If you go into a UKAT rehab centre like Oasis Runcorn, that usually starts with a medical detox so you can come off alcohol or drugs safely. Once you’re through the worst of it, the real work begins in therapy. You will have sessions that deal with both sides of your experience, looking at why you use substances and why you feel the way you do.
Some of that happens one-to-one, so you can talk through your history and what keeps repeating. Our experienced therapists can help you see the connections you’ve missed and why certain feelings send you straight to substances. The point is understanding what is driving the behaviour so you can do something different.
Some of it happens in group therapy sessions, with other people who know what it’s like. That can be a huge help, as feeling like you’re not the only one can give you hope.
If you need medication for depression, that gets looked at alongside everything else. Some antidepressants work well with addiction treatment, but our doctors and medical team can work with your GP to work that out.
You will then go on to relapse prevention planning, which looks at what you’re going to do when you leave, and what happens when you have a bad day, and the old urge comes back. Good treatment programmes like UKAT’s consider all of that before you walk out the door.
This isn’t something you fix once and forget about. Depression and addiction are both things you have to keep on top of over time. But it does get easier, and it starts with getting the right help.
