I agree about burnout -- maybe read up on burnout on the internet and start doing things to refresh yourself and build energy. Exercising outside every day is good for you and free.
I also agree about self-employment. I have been out of the wtbts for more than 30 years. I had no job skills when I got out, was cleaning houses for a living. I went to a trade school and learned a skill and made my living through self-employment. It has its ups and downs, but working for yourself is a darn sight better than working for someone else at a job you hate.
It took me some time to feel grounded and to know how to run my life after the wtbts, but it worked out eventually. I definitely recommend counseling -- I went to a psychologist and it made all the difference for me. It gave me boundaries, goals, ways to interact with other people and an understanding of how what I had been through affected my behavior.
Julia, maybe you can use your time off from the tourism job to explore some form of self-employment. Look around and see what the needs are -- maybe some of those tourists who own houses in your area need someone like you to look after their houses during the off-season when they aren't there? How to combine teaching and tourism? Maybe start taking burned-out teachers on retreats. I know a nurse who started that, she has been taking other nurses on retreats for 30 years now. Originally she did retreats in beautiful locations with lots of continuing-education classes so that nurses could combine continuing education with some relaxation and self-nourishment. Nowadays she still mostly draws customers from nursing, but they do lots of retreats to so-called "magical" places, things to do with King Arthur, for instance.
Kate, I'm sure you and your daughter would get some help from counseling to raise your confidence. Is it a possibility? I was amazed at how much it helped me. When I got out of the wtbts I was pretty beaten-down and depressed. I had pretty much given up on life, but that actually was a good thing. I got going again in a different direction with the help of my psychologist and some anti-depressant med, as well as some training in a new skill.
