I was sorry to hear about your problem. If I were you I would find another job. If you will be happier, just change it. You should do something you are interested in, and not something that is boring for you.
You must also stop worring! I think the best resolution will be to go on holidays. You should relax. And remember, this job will only irritate you.
I hope these advices will help you and everything will get back to normality as soon as possible.
I am looking forward to hearing from you,
