Hey englishteacher,
I can so relate to your post. Actually, I just posted something about work under the heading of anxiety. What is it? I used to work nine and ten hour days at times. I just don't have the energy anymore. I am going to try to keep taking this problem to my therapist and hope to work on it. I don't know if you can relate too, but I have found it so hard to get over any negative criticism. Mine came from my dad who told me I had never made any good decisions (about work). I just can't seem to drop that and it follows me around every day.
Have you thought about taking a "step down" to some kind of low-paying job while you "sort it out?" I have. Ugh. It's hard to keep up positive self-esteem with that decision, though. Have you done any tutoring kids on the side? I also like writing and grammar. I was thinking copy-editing sounds nice (stuff you can do from home). Have you ever seen any of those sorts of jobs?
