Changing job

I really need some honest advice.

I’m thinking about quitting my job because the person I work closely with is very difficult. They often try to offend me, scare me, and they don’t properly show or explain the work to me.

The situation is starting to affect my day-to-day life and mental wellbeing. I feel stressed all the time and I’m losing confidence.

The problem is that I’m also scared to look for a new job. With everything happening around AI and companies cutting jobs, part of me thinks maybe I should just stay where I am and save more money first. But another part of me feels unhappy staying in this environment.

Has anyone been in a similar situation? Did you stay for financial security or take the risk and move on? I’d really appreciate honest advice.
