I'm 15... ED question

I'm 15 years old.  I've never had ANY problem getting hard ever since I hit puberty.  One day recently I decided I'd hold off awhile on masturbating, because I thought my girlfriend was coming to town in a week (didn't know where that might lead).  Well, the week came and went, and a few days later I masturbated... I had trouble staying hard the whole time, even while watching porn.  I had only a lazy erection when I ejaculated... Yesterday the same thing happened, except that the full erection lasted an even shorter time.  Now I cannot get hard at all, no matter what.  I've tried everything: stories, porn, thinking of my girl... nothing works.  Help?

I don't think it could be a stress issue.  I AM pretty stressed right now, but that's never stopped me from being aroused in the past.  Perhaps I should also mention that I've only been able to sleep about 5 hours every night (I'm forced to wake up at 6:30 a.m. for Driver's Ed), and I've been catching up on about 2 hours around noon each day.

Update:  I just got hard for about 45 secs... I guess that's better than nothing ):

Sorry if any of this is at all graphic for this site.  I'm just really worried.
