Get over green day obsession?

i 1st heard of green day when i was 8 with my friend natalie. a year later, i bought their album dookie, but didn't really understand it. then i bought American Idiot this year & listened to it and i liked it, but not a ton. then i started listening to it more and more until it got to the point where i couldn't go a day without watching tons of videos on them and listening to their music. then it got even more intense. i get this weird feeling in my stomach when i'm not listening to them and when i am, i start daydreaming about green day coming to my house and stuff. then i get sucked back into reality and i get teary-eyed cuz i realize that'll only happen in my dreams. my obsession still goes on and i always am thinking about them. how to i stop myself from thinking about them all the time and stuff? i can't seem to pull myself out of it even for a few minutes. help please!
