It sounds like your dad may be trying to deal with something he doesn't know anything about, something that seems terrible to him, by making it something non threatening and hoping it's something you can just turn into a positive on a whim.
Your parents are just people like you and me and many times when people are scared they try to make something seem less intimidating than it is in the hopes that you'll see it that way to and maybe it actually will turn out to be less than it is. But that's not always the way life works.
If you're scared, tell him you're scared. Ask to see a professional. It can be an issue that medication can help with or it might be something therapy will help you learn to deal with or overcome. A professional will also give your parents someone to express their fears to, to ask questions of, and to glean information from in how to handle this situation. Remember, they've had no training in how to handle this. You're probably more knowledgeable about this subject than they are right now. There's no manual on how to be a parent and they probably don't want you to be scared or to know it if they're scared.
Hearing voices is something that can go away. I have faith that everything will be alright and you can get through this. Just take a few deep breathes and have a heart to heart about your feelings. Ask to see a professional and if you don't feel comfortable with that person, find another person. It's okay to shop around for the right one. Take care of you and if you ever need someone to talk to, hit up my inbox.
