I think I understand where you're coming from. About 5 years ago I was sent to a dual unit crisis center (treating both drug addiction and mental health issues). I was sent there after a suicide attempt and although I had only smoked marijuana they threw me in with heroin addicts and the like. Like you I smoked weed to help cope (for me it was major depressive disorder and anxiety.) I was depressed, confused, and in a haze from the excessive smoking. So I believed what I was told and accepted that I was an "addict".

I spent a whole year avoiding alcohol, weed, and even cigarettes. It gave me the opportunity to find new ways to fix my issues. When I was getting high to cover up my problems I still couldn't escape them. It was like being a teenager and sneaking out to go to a party: you're having fun at the time but in the back of your head you know there's a world of trouble waiting back home once the party is over.

In the time that I avoided drugs and alcohol I was miserable. However, my misery forced me to face my problems. I got an excellent doctor, went to cognitive and dialectical behavior therapy. I tried all those stupid pills that never seemed to work. Eventually I found the answers I was looking for through patience and hard work.
I still smoke weed and drink occasionally. But it's wonderful because I don't feel like I HAVE to. I do it because it feels good not because I'm hiding or escaping.

I make a point to never preach about this stuff because for all I know you may have already spent years trying to fix things "the good old fashioned way" and weed is the only thing that seems to work. Or maybe it really does make you feel better to the point where you don't need anything else. But for me it was not the miracle cure I pretended it was. And if any part of your story sounds like mine I would urge you to just take a little break if you can. See if you can't find something that works better than marijuana. It was a crappy road to recovery for me but it was worth it.
