Please do not resort to binging purging or starving in any way. It's counter productive, I have suffered years of eating disorders when I was younger, and when it was all done, I gained 100 lb. And then I started losing it the healthy way.
If you want to speak to someone you can talk to your mom, if you have a good relationship and are close to each other, you can tell her you're trying to lose weight maybe she has some tips and tricks for you to stick by. But please don't harm yourself in any way.
It's not worth it.
If you want, add me as a buddy and write to me, I'll even give you my email address and I can be there for you if ever you feel like something's wrong.
Keep your head up, tomorrow is a new day
