12 here, I don't think you sound like a bitch at all, your concerns are completely warranted. I actually kinda agree with you on the whole mental health service, some people do have negative experiences with it. Though I wasn't really referring to the medical psychiatrists who prescribe you drugs and put you in hospital but just a guidance counselor.
But yeah, having been through that stuff myself, I personally wouldn't go to see a counselor again, mainly because I prefer to work on my problems myself. They do help many people though which is why I suggested it.
I recently saw a online textbook, I haven't really had a good look at it yet, but thought it might interest you anyway.

This place is all about the whining so continue doing it if you think it helps you.
