I feel like I fuck up my life at 18

I'm 18, soon turning 19, but I don't feel like an adult yet. I still think like I'm 17, and it's confusing. I can clean the house, but I don't know how to wash my clothes or cook, I don’t have a work (yet I’m looking for one). I've never gone to parties, don't drink or smoke and never even tried, and I'm still a virgin. I'm going to community college, but I feel behind everyone. I've always struggled to make friends, and after an issue with my ex, my old friends stopped talking to me almost one or two years ago… and I still can’t make friends. I worry it's too late for me to catch up, especially with turning 20 next year. Who would date a girl living with her Christian parents? And plus is scared of intimacy. I feel pressured to go out and party, even if it’s not really my thing, because that seems like what adults do or people of my age do.
