Where do I start?

I’m 21 years old and I’ve gone through a lot in my life and it’s made me super depressed. I’ve been living with my boyfriend and he works and pays our rent and bills and I literally stay home all day doing nothing. I do clean and do his laundry the little things I can do. I feel like I’m ready to do something with my life and I need to start helping my boyfriend out. I have no idea where to start though I’ve never worked and don’t know what to do. I also have the worst social anxiety. Any advice ?
