My boyfriend belittles me

I got my first job back in June as a cashier at Walmart and I had a panic attack cashing for the first time and couldn’t do it anymore so I had to quit and ever since then my boyfriend brings up the fact that he works a does better than me and I can’t keep a job because I’m stupid. Today I told him I have an interview at target and he just laughed and said you’ll be jobless in a week.
