Cause of my tinnitus?

ok so i got tinnitus 4 months ago and i finaly came up to first on the waiting list and got into a doc, now this is the oldest most arogent doctor you can imagine but basicaly i walked in and he put in earbuts that beeped and i had to push a botton everytime i heard a beep, so once that was done he said that i have perfect hearing with no loss. then he put wire stickers on my head and the earbuds clicked for 4 minutes. he then said that in my ears there are little piston like things and they have the responce and wear and tear that should be seen in a 40 year old(im 17) he then said my ipods to loud and nothing can be done, he said us punk kids with our "hip hop" and vibrating cars come in alot and its the same thing. but i was also diagnosed with tmj and clenching my teeth at night since before the ringing. is it possible that i have worn out ears from music but not damaged to the point of tinnitus? he didnt help at all and got mad when i asked if there was any treatment. if i push my ears hard and fast with cupped hands the ringing gets super loud than goes away for a few minutes. also the ringing always changes and goes from ear to ear. do i realy have perminent noise induced tinnitus or is it from my jaw and clenching? im at the brink of suicide because this ******* ringing wont stop!! please shed some light, what can i do!!
