You speak for many here when you say that you are over-committed. I think most of us (in this forum) are 'people pleasers'. My husband helped me see how overcommitted I was and I finally learned how to say no. I actually get more respect now than I did when I was a 'yes' person. Even at work, I got more respect when I set clear boundaries and realistic expectations for myself. I gave notice that I could come in early, but not stay late.
Cloudy, it sounds like you have two full-time jobs. School is full time and so is work. If you don't speak up for yourself no one else will. (BTW, I was always committed to getting 4. average in college and it turns out that there is no kudos out in the world for that. It is a self-satisfaction, but at the expense of a whole lot of energy)
I think lots of us end up in a tail spin by over committing and not being able to say "sorry, but NO, I can't" .
