sometimes talking to a parent is the most helpful thing
cause u
know they will care for u, they WILL try to help u
they will want u to be better, and sure will have more experience to help than ur friends [who are at ur age after all, why should they know better than you?]
now i think that if u think they would be able to help u, u should just talk to them
u could say "i want to talk to you about sth serious and i need for ur advice"
[u are kind so they will accept everything easier]
then u say: "now, i know its weird but i d like you to tell me... [blah blah blah]..."
if u dont feel comfortable talking to them, and ur friends are not a help either u cant do many things.
u could post it in an advice forum so as sb to help u, or ask sb elder than u, or some person [maybe even from ur family-uncle ets] that u REALLY trust to help u...
i dont know what exactly ur problem is so i m not able to help more

but i hope i helped ya!
