Is it normal to be really scared to go to work?

Ok here's the thing, I got a job in a pub months a go and my boss was really horrible, they gave me no training and left me on my own to work the shifts on my own. He was really inappropriate and asked me to work with no top on. He told me I was useless at my job and I cried every night when I had work the next day. I quit that job after a few months of hell but now I have a new one. It's completely different because my manager is really lovely. The fact is though I'm still really nervous about going to work. I had my first shift yesterday, I made a couple of mistakes. pouring the wrong drink and clicking the wrong button on the till but nothing major. I feel terrified to go back tonight :( is this normal?!
