Ok, I just talked to my Mom. She said that she’ll make an appointment with an OB/GYN for the next day off she has. She’s pretty concerned about it, so that’s one hurdle taken care of.
But I’m still scared.

It’s okay to be scared. The thought that there might be something wrong is a scary one.
Since you’ve decided to go to the doctor, can I make another suggestion? Be sure to see the doctor ALONE, without your mom present, and if you can, take the opportunity to discuss with him/her the other stuff going on in your life. Hormones may be only part of the problem, and the doctor may be able to give you some good ideas on how to deal with any other issues.
