I've recently started a new job (Monday) and I'm currently on an 8 hour contract, and I understand this means that I have to work at least 8 hours a week. I did an 8 hour shift both Monday and Tuesday and honestly I'm drained. As well as this, I experience significant anxiety, and it has been unbearable both before and during work - I had to call my mother yesterday morning because I had an anxiety attack and was almost sick (I now have a Drs appointment regarding anxiety).
However, over the next three weeks, I've been put on four 8 hour shifts a week, and next week these shifts are all in a row. I could barely cope with the past two days so I really don't know what to do about the next few weeks. I can't physically and mentally cope with working these hours, but I'm not sure if I should say anything because I'm new to the job. I'm thinking of emailing my manager, but I have no idea what I should write in the email.
Please help!
