What phobia or disorder do you thibk i got ?

I have the fear of going in a place were people are alone or going to a new place alone. Like my friends house and Idk why but I don't like to be the one to shut their door but ill open it. I don't like standing in line somewhere alone that I haven't been to. I don't like walking in a room full of people. This has stopped me from driving I'm 17 and just now started but I was scared of wreaking. And I'm also nervous about starting new relationships. I won't take the trash out alone. What phobia or whatever do you think u have? It has also stopped me from getting a job in fear of messing up and doing something new and messing up
