Any advice would be great

See I have been having problems like this except for im 16 and now I swear that I have anxiety or depression and I am going to force my mom to take me to the doctor.

my fiance is a paranoid schizophrenic.
it started when he was a teen...apparently it often does.
I'm not saying you have that, but it's one of the possibles.
good luck.
