I think, (Though I know people have given you lots of advice already) Stick to what you are doing. Don't you dare! start throwing up on purpose. Wait for the doctors appointment. They will try to help you.
I find myself being hungry all the time and never able to eat. My stomach has been having all kinds of problems lately. I may even have an ulcer. For the longest time eating caused lots of pain, and (The doctor is helping with pills and blood tests, I've gotten better) I couldn't and didn't want to eat. I've lost a lot of wieght. At 5'8" I am about 104 pounds. I miss the 20 I lost.
Being skinny, is NOT what its cracked up to be. Throwing up is the worst thing ever, and doing it voluntarily... no way. It causes so many more problems than it can fix.
Not letting yourself eat at all? You'll be in pain Constantly. It's horrid.
So stick to eating small meals, and more meals during the day. Exercise. Wait on your doctors help. Keep encouraged, and listen to your close friends who are telling you NOT to do it. Besides, if they do tell your mom or a teacher? You'll just go to rehab or something worse. And that wouldn't be any fun would it?
People find out about what you're thinking about doing? They'd just whisper about in the hallways, and make fun of you, and joke about your gagging yourself, and all such horrid things. I've realized that people who make fun of people aren't worth the time it takes to realize they exist.
Also? Boys? You'll find the right one eventually. He'll love you for YOU no matter WHO you ARE, or WHAT you LOOK like. That's the point in the first place. You're only 13. Wait. Life is wonderful. Don't ruin it.
So listen to all of us on here. We want to help.
And the four who voted yes???? Someone HURT them!
