It's a production job and my first job that is outside of retail and customer service. I'm so anxious and I can't sleep.

I already left 3 other jobs in the past 2 years and I'm worried that I will dislike this new job and quit within the first few weeks. Repeating the cycle. My old jobs made my mental state suffer and i quit easily without giving it more than a couple months. 

I feel I used up all my get out of jail free cards and now if I go into work today for my first shift and dislike it, I will be forced to just deal with it. If i dislike it, there is no way out this time.

Anxious to start work and anxious about what to do if I dislike it. Any advice?
