ok, real quick, totally off topic:
does it take awhile for these things to go from Pending to Active? I made a post this morning and it's still pending
ok, on topic: I'm sure you have health insurance through either your mom's or dad's plan. if you do, you should have a card. I suggest looking at that card and calling the 800 number on the back and asking for behavioral help. i know in california you won't be able to make an appointment or anything (i believe) because you aren't 18 years old, but i don't know about other states.
go see a psychiatrist/psychologist. there's NOTHING wrong with seeing either i've been to both and have had many a dark day in my life. i'm not here to diagnose you or anything but explore your options. you can get help, you just need to ask for it.
your parents laughing in your face is plain wrong. you are their son/daughter, they should be there for you no matter what. if this is affecting your life and is bothering you they should be there and HELP you.
