Tony, I'm sorry things are so rough for you now, but I don't think that going back to smoking is going to help them. It is very hard to face reality, I know, but things just get more screwed up when you do it high or drunk. There are lots of sober people out there who will be your friend, it will just take some time to find them. And maybe your family will start treating you better once you get clean. You could join your friends and go back to school and be one of the people who just come back to town to visit!
