I don’t think I can stay in this job.

I’m so early on in my career (2nd year) but I am already feeling so exhausted. There is so much to do all the time and I feel like I’m just being left behind. I thought it would be a little easier but I feel like it’s just an uphill battle and I am so uncomfortable in my office. I literally had a student today day in front of the entire class our last teacher didn’t do that why should we and I want him back. And I feel like I have so little support in my office and I am just worried they are all waiting for me to fail. I want to move offices but I know there isn’t desk in the other 2 offices I feel more comfortable in. Plus I’m marking senior school work and just hoping I’m doing things correctly. I’m so worried about stuffing up the ranking later this year and not getting help. So many people say this is the best school in the area but some days I don’t agree. How have people survived years in this profession? I feel like it’s sucking the life from me
