I'm in a very similar situation to you. I suffer from depression but can't pinpoint exactly why. One thing I would recommend is not to self medicate. Its a short term solution which will only make it more difficult in the long run. I've been there. I used to get high to feel better too but its just not enough. Unlike you though, when I feel this way I hate being alone. I feel like I need to surround myself with people or activities in order to attempt to take my mind off it and focus on other things. Maybe doing the same will help you? Seeing a counselor is obviously something that should be considered if you think it's that serious. Having someone to talk to that will listen and try to help is very important. I also find that online support communities such as this are very helpful as well. It's nice to get anonymous support and be able to discuss how you're feeling without having it be someone you know. It's also nice knowing that you're not alone and other people are suffering from the same problems. The worst part for me is not knowing why I feel the way I do. I feel like if I could pinpoint an actual cause for feeling depressed I'd be better able to cope with it but I can't. I just randomly feel this way and can't seem to get rid of it. I hope you feel better and continue to post.
