I got terminated from my job? I think depression is going to start happening again.

I'm young I'm 20 years old I was a ballet instructor and I worked for the city. My sister gave it to me because she worked there easy job you teach little girls how to dance for 2 hours and you can get paid like 400 or 300 depending how many students you get. Well I was terminated because I got complaints from the parents because I was repeating the same steps over and over again I've been dancing since I was 4 years old I had experience and when I was dancing as a little girl my teacher would teach me the same thing it's a process where you see the student growing and see if they are improving the steps until they advance to the next level cause the other levels I teach are advanced where the girls who are aged 4-6 can not do because for their safety I would not want them to injure themselves by doing more advanced stuff it's only basic. I was a independent contractor but I knew what I was doing. They said if they can't find another dance instructor they will call me back but I doubt it. But long story short I already applied for 2 jobs but this job meant a lot to me I feel like a failure I'm stressed I've been struggling with depression for years and I feel like it's coming back I just can't 😪
