Password problems

Welp theres a problem on my hands. I CANT SIGH ONTO MY PS3!!!!!!!! Yes, i screwed up. I was trying to figure out what my password, and i ended up erasing my password, and i dont know what it is. OK, after i ihad my HUGE spaz i figured out that all i had to do was click "forget password?" but then i realized that when i set up my account that i had entered a different b-day than my own. so....what do i do now, do i have to just set up my new account? or is there someway for like Playstation Network to send me my password?
