Princess, looks like you feel fed up. You say you don’t care. Perhaps this is the root of everything. If I understand correctly, you weren’t as upset that you couldn’t do the sport but rather that you’re restricted. You feel like somebody is leading your life for you. Why, that sounds SO familiar to me! But PLEASE DON’T do what I did. DON’T drop it all. Do some research. Look, you want to find happiness, right? Check it out. I can’t post everything on a public forum, but I think you should read “Permission to Believe” and “Permission to Recieve” by Lawrence Kelemen. Also, research all religions. It might help you. And perhaps you can do some research on Evolution. You’ll see how contradicting and senseless it is. When you’re not certain that Yiddishkeit is in fact the Truth, you feel that you are restricted and you feel sheltered. OTOH, if you do some research and see that this IS THE ONLY SENSIBLE RELIGION you feel privileged and you see the beauty in Yiddishkeit.
Good Shabbos and Good luck!
