Depressed teen without friends?

my daughter has eliminated all friends in her life. she gives them up easily little by little as she has a zero tolerance for drugs and alcohol and at age 19 thats what they are all starting to experience. shes a tad mature for her age and has no patience for teenage drama. her boyfriend of 3 years just broke up with her as they fight all the time. he hates the fact she doesnt have the same resposibilities he has. she works and goes to school and her earnings are hers to spend as she wishes. his income supports him. he has to buy all his own in everything even tho he lives at home too. hes jealous that she doesnt have to support herself. she is in college and i feel that is her only responsibilty for now. she does make her own car payment and pays her own gas and 1/2 of her insurance. anyway back to question. since she has eliminated all friends and doesnt have much free time how can she make new friends? she cant really go to the bowling alley or movies or shopping or even to a club by herself in hopes of meeting friends and she doesnt like sports. she is getting severly depressed that at her age she has no friends when all her life she has had a ton and has always been popular. she really is a good person she just doesnt like the party scene that all her (x) friends seem to like. i would love some advice to hand her but i dont know what to tell her.
