New teacher and New Yearbook Adviser. How to establish authority.

TLDR: I need one more year to clear my credential, and I don't know if I will last. I'm in my 30's and this is the most stressful, all consuming thing I have ever done. I am a people-pleaser and capitulate too much to my students and editors. I don't know how to establish authority and for my Yearbook students to have confidence in me.

S0, this is my first year teaching. I was fortunate to long term sub for this same school last fall and continued in the same classroom for my student teaching that following spring. Now, I am almost done with my first official year as a teacher. One of the things that got me my job was that I knew the Yearbook adviser was stepping down, and I mentioned I did Yearbook in college.

I have tried so hard with Yearbook. We are now a week late on our submission. We are so close to being done. I arranged a work day last Sunday. I told my students that if they were not sick or out of town, I expect them there. out of 22 students, 6 told me that they couldn't make it. 6 out of 22. I was there at school for 6 hours waiting, and no one came.

That night, I got the stomach flu, or so I thought. It was just stress. I called in sick, so I didn't see my students today. We could have gotten the entire clean up of the book done in 2 hours and now it will take the entire week to get things done.

I am naturally a conflict avoider. Even though I am the adviser, I capitulate to my editors. I know that attitude does not help students to have confidence in me. I decide things, and in front of everyone, my editors contradict me. When I disagree with them, I talk to them quietly and aside to not undermine their authority. They do not extend me the same courtesy, nor do they trust me. I know it is hard to do things differently from the other adviser.

I don't know. I am in my 30's. I have had a lot of jobs. I am on a temp contract at my school. I do not know if I am rehired or not. I am tired. I have never been this stressed out. I am more stressed than when I moved to a foreign country where I didn't know the language or anyone. Teaching, managing teenagers' emotions, politics, parents, all of it is more stressful than any job I ever have had. I need one more year to finish clearing my credential. I have gained so much weight. I am feeling sick all of the time. I am not really ever happy.

Last year, I was insanely stressed out. I felt sick every day. I cried nearly everyday. This year is better and worse. I am just numb. There is no joy. I am just waiting for the other shoe to drop. I am waiting for the irrational parent, for the lawsuit, the blame. I don't even know if I can do it for one more year. How do you all keep going? How do you establish authority and trust with your students? I am not an introvert, but I am a people-pleaser. If any of you also are, how do you balance that with classroom management and authority?
