Unable to make friends

I can’t make friends, I don’t know where to make friends, the people I work with are stuck up, my boyfriend is super busy with school and he’s in the same boat as me no friends, my one best friend only hangs with people over 21 because she is and they only hang out at bars but I’m 19. Otherwise she’s home with her man and her baby. My roommates are older then me and we haven’t been successful in finding me friends. I just don’t know what to do or where to go. I can’t drink and I don’t like it, I don’t want to go on apps like tinder etc because it’s all about sex and hooking up and I’m taken. I just want people to adventure with that are chill with what I’m chill with. Or at least people to talk to, I need to keep busy and I miss having people to talk to. I’m not in college yet because I’m saving up money to afford it. I need friends and I don’t know how to make them. SOS lol
