Yeah I don't even really wanna be a teacher. I just want to step back from crazy and continue to train in an art I sunk nearly a decade of my life into.
The "nearly a decade" is sunk costs. You can't get it back, and you shouldn't base your decision to stay or go on the value of that time. Nor should you base it on the likelihood of promotion, given your messy situation. If you decide to stay, do so because you like the training -- however, even if you do decide to stay, I think it would be wise to investigate other options. If nothing else, it will give you valuable perspective.
