Music_Rules_Me, I know what you're going through.
I feel that way all the time now. As you said, "not particularly sad, just numb".
Doctors scare me too. They might diagnose me with something awful, or try to prescribe some medicine that will mess with my head.
But counseling helps. You say that you want to talk to someone- there's your solution. Their job is to listen to you, so you don't need to feel like you are burdening them with your problems. And they can give you tools to help keep the sadness/numbness away. It can be scary to talk to them at first, I know. (And I don't think anyone knows that better than me. ) But it gets better, trust me. It gets a *lot* better.
I hope you find some help, and start to feel better!
