What if I’m not good at anything?

So I work at a school and it’s starting to take its toll on me. I feel trapped and almost like it’s starting to spill into my personal life. I feel like I live for pleasing my boss and I’m tired of that. I’m looking for new work but so far there’s nothing I can find. I’m starting to realize that I get sensory overload and I might not be able to take the stress anymore. I feel like if I can’t handle this job I won’t be able to handle anything else. I’m still going to school and don’t know what to do anymore. I guess I want support and to know I’m not the only one who feels they’re always messing up.
