WHAT CAN I DO TO STOP THIS SILLY ADDICTION/OBSESSION?

For about more than a year now, i've had this obsession with listening to loud music on my radio with the speakers (not ipod with headphones) on more than half. I do this while jumping on my bed. I cannot help this. In fact, when school ends, i have this big urge to just come home and do this. For me its like a stress reliever that boosts my confidence and makes me feel good about my self. I don't even feel like going to any extra-cirricular activities for school, because something inside me tells me it needs the music and the bedjumping. It doesnt do anything if i only listen to music, i HAVE to jump on my bed too, same thing the other way around. My matress is beginning to fall apart and the springes are beginning to pop out. I just dont know what to do. So i switched to doing this in my parents' room. I lock the door. They dont hear me jumping because the music covers the sound of me jumping on the bed. I can't control myself. Without doing this, i feel sick and really stressed. Its like a really big urge. I can't explain it. What can i do about it? I've tryed stopping for a long time, but then i just end up doing it anyways. Today i was commited to not doing it and was only successful for about 2 hours after school, then back i was to doing this, and it makes me feel so good too. I cant explain the feeling. Also, the starnge thing is, i've been listening to the same music as well, and i never seem to get bored of it. I dont want to ruin my matresses and hearing as well- more importantly. What can i do about this? help please!
