I think I'm completely unhireable

I have been attempting to get a job for 2 years now, gone through recruitment and help services like AZ@WORK and MLK but those have gone nowhere. I have friends but it seems like those connections haven't been able to land me a job. I somehow managed to get rejected from field work and other job fields you wouldn't expect to get rejected from. I have a little job experience and I'm 18+ with over 250+ counted applications both in person and online. I am not entirely sure what to do anymore especially since I don't have a car right now and when I have it I have to worry about insurance money (which will be expensive since I'm a newer driver). Is there anything I can do or am I just completely screwed?
