your story reminded me of of myself when I was your age, I could not get a doctor to
take me serously, but when I was your age it was a LONG time ago. I think the medical
feild has gotten better sence then.
I would go into a doctor and tell him what was going on in my head( what was very hard for me to do cause I did not like throwing my heart on the table just to have some doctor not belive me) but there is help out there and there is some good meds, so dont give up keep looking you will find the right door to go through, and right now if a little weed helps, then keep using it intell things fall into place. Just remember you are not alone.
