Welcome to PC. You might check out the depression section too.

It is possible it is causing them. Or you are self medicating and you are finding that doesn't work. Or you are dual diagnosis like me and so many others. I started getting depressed and would not go out and hang out with friends when I was 13. At 14 I was drinking and smoking pot and was out with my friends every night. Drugs and alcohol worked for awhile until it didn't and I was left full of self loathing and depression. I was a black out drinker and the shame of it all was tearing me up. Two classic symptoms of an alcoholic are black outs and what is called the phenomenon of craving. Meaning that most of the time once I started drinking I could not stop. Get the pump primed and off we go until all the booze is gone and all the stores are closed. Then there is the mental obsession. Meaning by the next weekend when I was feeling good again I just could not stay away from that first drink. One is too many and one hundred is not enough. That last sentence sums it up pretty good. And oh yes, many other drugs went with it. Cocaine, Meth, it didn't matter. I can tell you I have been clean and sober for 19 years and have been treated for my depression for the same time. I won't tell you it is all a bed of roses but it is soooooo much better than it was then. I am very grateful for that.
