...I did and it's so not worth it. Fifteen years of giving up everything - family, life, etc. No-one appreciates it - parents say thanks and move on. The school moves on when you've left - very quickly. I had a few warnings, but never really thought they knew what they were talking about. It was MY job and everything mattered. It doesn't. Life is so much more important. It's a pity that I didn't listen.
