Mental Illness and Work

I began a new job at a plant. It's only been a week, but every single day I am paranoid and have constant gorey and depressing intrusive thoughts that it will explode or I will get injured and disfigured or I will slowly get a disease/cancer from the fumes and particles. I'm starting to sometimes think I see things out of the corner of my eye. I start hallucinating under enough stress and thinking that I see things/people that aren't there from the corner of my eye is usually where it begins, so I'm worried about where that may be heading. And since I have autism, the sudden noises and change in my schedule also overwhelm me to tears and breakdowns in private. This job pays well, gives insurance, and is pretty decent workload-wise. It's only my second job ever (I'm 20) and I'm not even done training. I want to be a computeer engineer in the future, and this is a great start to learning a few things as it gets me around different machines and stuff. I thought this job would look wonderful on resumes, and the work itself is somewhat laidback, but my stupid fucking brain doesn't work right. Am I too psycho and autistic to ever just have a normal fucking life and be able to work a damn job? This shit sucks and it makes me want to just kill myself. Should I quit or something? What should I do? I need money and I've been needing insurance for so long.
