job anxiety

I’m 17 and I think it’s time I get a job but I’ve never worked for anyone other than my parents and it’s make me really anxious. I’ve previously cleaned houses and babysat, but I’m avoiding fast food jobs (which is difficult cause almost all teen jobs are food related) and gas stations. I’m pretty sure I’m overreacting but I’m just terrified to get a job because i get nervous around people I’ve never met and because of things that happened to me in the past I don’t like being alone with new people either. I also suck at math and hate being put on the spot, being the center of attention in general irks me but I always assume the worst. I just feel like I won’t be able to handle the stress of having a workload,or be able to perform the tasks they ask. My other option is to wait till I turn 18 so I’ll have a better chance at being hired, and possibly be over my anxiety, other than that any tips ??? :,)
