just wanted to welcome you to PC, and I think the others have given good advice. I don't have too much to add, except that sometimes when a task seems too huge to accomplish, its good to break it down into mini steps. Are there some habits you want to get rid of? Can you pick some days that you are NOT allowed to do these things, can you add some positive things to your schedule? Can you promise yourself that you will go out with some other friend at LEAST ONCE a week (or whatever goal you want) to start establishing healthy friendships?

ps you mentioned that you weren't sure this thread was in the right place - if you want it moved you could always PM a moderator or admin =) we're here to help
