I need some help

Bethanee

I'm go to try to make this short. I'm in high school (16 years old) and I play softball so I have to go to the weight room (the coach is a guy and is the health teacher at my school) and I get really bad cramps to the point that most of the time i start crying because it hurts and my grandparents do not let me take anything for the cramps are let Me do any thing to try to stop them and I was at weight room today and I'm on it now and my weight room coach knows that I have sclosis so he came up to me and says does your back hurt and I said no. And he says OK let me know if it does start hurting and I said that I would. And he was talking to the other coach and I over heard say something about me and he said has bethanee said anything because i know that she is in pain and she is not telling me so I do not know what to do. And I do not know what to do because he is now worried about me because he is the only person I feel comable talking to so I feel like he is going to say something to me about it and I do not know what to do in really scared right now I do not know what to do now can any one have any ideas. And I have no one to talk to at home because they to not care that I have questions about what is going on with me. And I'm really sorry it is long.
