Confusion!?

Well, here it is a year and three months since surgery day...I FINALLY know my limits on food! I can still enjoy all the flavors that I love, just a whole lot less! I know I can only eat a small amount and don't try to push it with that "one more bite". I started exercising by doing the C25K. The first day it went well, the next time, it was really difficult. Now I am afraid of failure so I haven't been back. I think that I get so afraid of failing that it is easier to just not try. However, I had a really long ride to my sister's house and then home and I did a lot of thinking. I need to do it and failure is not an option. Tomorrow I will be back on track to my 1st 5K. I am so excited for this summer with the new house and my new self. I think it is going to be the best one in years. I look forward to Niagara Falls, swimming at dad's house, and fixing up this house. I love that I am in such a good place. Now on the other end...physically I feel awesome and things are looking up for me. However, my psyche is not doing so well. I keep thinking that I should no longer teach. Since I am not allowed to write anything in here that could make my coworkers or students look bad, I will leave it at that. I love teaching, I love when that light goes on in their head and they get it...I love laughing with my students and I love being there for them when they need me. What I don't like is when parents and staff members judge me and want me to be who I am not. When they think it is so easy and they haven't got a clue. I hate when people don't understand me and they don't try to understand me. I REALLY hate when I am judged and the judgement is unfair. I only want everyone to be happy and if that is a crime, fire me and quit dragging me through the mud all the time! I really have lost all my self-esteem this year and it hurts to the core of my being! I did not know that teaching was so full of politics...I thought that the union was there to back teachers and not the administration. I am really, really sad that I hate to go to work! The only time I am happy is when I am teaching my students and they are having fun...with our crappy curriculum I barely ever get to teach and have fun. I am forced to test students,do interventions, and teach to the lowest 35% of the students in my class and the other students feel cheated. I get it, I hate it too. I tried to switch positions and to find a place where I would be happy, but that was pulled out from under me too through political bull-crap! So what do I do? How do I get my self esteem back, am I that bad of a teacher? Do I believe what people say? I am so sad...is it worth the pain to continue doing what I love? I have tried to stay out of the politics, but you just can't...it finds you! Well, life is so confusing...am I a good person, or bad...am I a good teacher, or bad...am I a good coworker, or bad, am I a good friend, or bad...am I a good mom, or bad? Confused and right now I am not liking myself at all...but hey I look better...or do I?
