Do I have DSPD

[DakotaM]

I'm going to say this now, there was no warning to it. I just suddenly couldn't sleep, i didn't mind it at first but then after a week I've become suspicious .
Well i'm 14,
I'll get tired around 11 pm to midnight, but then at 1 ill suddenly get as hyper as a child. Yes i've tried going to bed at around 9 like I used to do but i wouldnt fall asleep.
I normally now fall asleep at around 2 to as late as 5 am now and I would sleep sleep until noon, If I try to wake up before then I get dizzy and I normally pass out.
My parents have tried waking me up in the morning telling me that I just said "i don't wanna" or "I'm tired", and normally pass out after although I have no recollection of this happening. I've tried talking to my parents about it, they say its just a phase your going through. This has been going on for a week now, and every night I'm stuck laying in bed trying to sleep but I can't. I heard from a friend who did some research after I told her what was going on. She found DSPD and thought that this was what I had. If anyone could confirm this I would be grateful
