How do you deal with being in a group of people you have nothing in common with?

Well, why don't you go around with otherr people also. Do you have any other friends that you can spend time with too? They might have more in common with you and you can also go around with your boyfriend sometimes if he stops drinking and doing drugs. Find someone else to talk to and talk to someone else after that. Get in some groups about different things that you like. Take a course at school on something you like, such as music or art and try to find some kind of work to keep you occupied so that you are pretty busy. Think about someone else too.
