Wow I'm so sorry It's terrible how one person can have such a negative effect on you. I'm impressed by your strength though! If my coach was mean to me I would probably quit haha.

I am going to mention though, unlike a lot of people who have posted before, sometimes it IS a good thing to stand up for yourself against her. Of course the timing and phrasing of your words is important too. One time there was a classmate that would just harass me and after being quiet and just ignoring them for so long, I snapped back with a witty comment one time in front of everyone and it was so good that he never bothered me again. Of course, since it's your coach you'll have to pick your battles wisely but don't let her put you down!

Best of luck!
