Thanks for all the feedback guys, much appreciated.
I think I may have overlooked how difficult it was going to be to move back. After living on my own since 18 it's a big change, which is probably why I am getting so frustrated. Add that to the fact that my long standing self destruction crutch has now been removed it all makes a bit more sense in my head.
At the end of the day, living on my own did me no good so it is probably for the best I am here for the time being, with people who care about me. I agree with you all in that it's probably best for me to just put my cards on the table. They probably have no idea and think they are helping. I can imagine it's hard for them to know what to do / say around me sometimes.
CBT is a very good idea. I shall mention it to the doc tomorrow. I imagine it will tie in quite nicely with the SMART I am doing since that is also primarily CBT.
I will keep on truckin!
Thanks all
