Constant annoying urge to pee?

So i've had this constant urge to pee for about 2-3 weeks now and it's seriously ruining the quality of my life. It has completely obliterated my social life and school is really tough to get through (I'm 17 by the way )

I have no symptoms that could suggest either Blatter infection or urinary tract infection. I have no soreness, burning sensation or any of those. The only thing is, that i constantly have the urge to pee, but can't.

I've been to the doctor to get antibiotics, but they didn't work. I've taken numerous tests of my urine that were all negative, and I'm running out of possibilities. I've also tried drinking tons of water and completely emptying my blatter for two days straight, but no difference.

TL;DR: Can someone please, for the love of god, give me a magic trick of sorts, to stop the urge? Thanks in advance...
