Hi KitCat~

Welcome.
I agree with the idea of printing out this thread and taking it to someone who will listen.
You hadn't stated exactly who you have approached with your troubles and have addressed those individuals as "they". Are "they" your parents, or other adults who are in a position to help you? Or, are "they" your peers, who will assumingly simply not attend to your needs as they should be.

As always, begin with your parents for help. If, for some reason that is not possible, then your next step is to approach an adult who you trust that can help you to obtain the medical attention you require.

Teen hotlines are a great source for direction as well and perhaps that can be an avenue through which you can seek assistance.

Keep us informed as we all do care.
My thoughts are with you.
