Help

I’m a 36 year old, middle school art teacher in San Antonio. I started 5 years ago, and this year has got me to my wits end… my degree is in theatre and before teaching I was in service industry a majority of my adult life. I feel stupid, and unqualified for anything that’s going to pay me the same or better. And going to school for something else I feel would add to the burnout and/or the things I ‘want’ to do are either not financially worth the time and effort for a second/advanced degree or will take 10 years to complete… can anyone give me some specific pointers on how I can get out of this?
