need help making friends

I have social anxiety and feel like it's so hard to make friends. I don't have any girl friends that I hang out with anymore. I commute and work full time which makes it hard for me to go to events for school, etc. how can I make friends? It's really annoying when my boyfriend hangs out with his friends because I'm jealous he has friends. All the friends I've had have fucked me over or are just major bitches or overall toxic. Help me ladies!
