How to delete myspace???

I made an extra yahoo account just for myspace. I didnt go on the account 4 a while so i THINK it got deleted because i tried all my pwords (current and former) and i couldnt log in. i NEED to delete my myspace! they said theyll said an email but i cant log on. i tried making another email with the same name but it said it was taken! what should i do now??
