You have other people to talk to you just think it will be awkward. You need to go to someone who knows you. Your father might be weird to talk to about this but i guarantee he will know what's going on.
Hoping on a forum and bringing up a subject like this to a bunch of complete strangers is not the thing to do.
If you can't talk to your dad then have one of your parents schedule you an apt with a doctor because they will definitely be able to help and are non judgmental.
