Disenchanted?

I have wanted to be a teacher since I was 10 years old. I can't imagine being anything else. I've had 2 full time teaching jobs (12 years experience) - one at a charter school and one at a private school....and both have "issues." At the charter school, parents told me what I could and could not do with my day (including walking in with lists of words I was allowed to and not allowed to use during specific units). At the private school, I have parents who think they 'own' me because they pay tuition, and a co-teacher who is actively campaigning against me. I am starting to become disenchanted with the teaching profession. I *want* to be a teacher, but perhaps I should do something else. Maybe my expectations are too high? Maybe it's the leadership at my schools?

Here in Colorado, schools are all school of choice, which means when you first get a job, it will be in the really icky schools that nobody wants to work at. This lasts for 3-5 years until you can get into a 'good' school.

I'm trying to figure out if I should stop teaching and find another profession, or if I should chance public schools, or if I there is something I can change/do to improve my situation.

Anyone else been in this place? What did you do? Any tips or helpful hints in dealing with the possible loss of your lifelong dream? I love teaching, but I am not sure I can continue dealing with the baggage that comes with it.
