Don't know what to do.. advice?

Okay, it seems like your family is way too together. Also, you seem like you really need some ALONE time. Maybe a vacation? Have you ever tried to have a very serious talk with your family? I'm sure your brothers feel like you. I think your mom is very dependent, wants to hold on and isn't very socially inept. Why don't you try introducing her to new hobbies or people. Sometimes a pet can help. If all these don't work, you may want to see a therapist. Because after you move out (if you do..) it seems like your mother might have serious issues. I hope I helped.(:
