How to get over irrational job anxiety?

im 22 and I've only had one part time job and quit that 2 years ago. I was a cashier at a bakery for almost 2 years.

since then I've been meaning to get another job, but I've always put it off. I've got depression and think of the worst case scenarios whatever job I could possibly get. For example, what if im in the shop all alone and someone robs me/attacks me? what if someone sues me because they slipped when I was mopping etc.

Again irrational, and honestly that stuff can happen outside of jobs lol.

Even when im not irrationally overthinking these scenarios, I know it'll take a long time for me to settle into the new job. At my last job, it took me 6 months until I didnt feel constantly on edge from micromanaging, and making mistakes. I was constantly anxious during that time.

Any retail sales jobs I can't do because I really do not have the ability to upsell people lol. And food places can be very intense and I dont seem to do well under stress (morning coffee shift horrors)
