How to stop feeling like I have to pee in school?

Im Really Stressed Out Because Of All My COursework :[

At School I Need To Pee All The Time But We Arent Aloud To Leave Our Lessons Which Last For An Hour :[

Is There Anything That Can Stop Me From Feeling Like I've Got To Pee All The Time??

Thanks x

you might want to go see a doctor, because you could have a blatter infection!
but if not it might be the stuff you drink!
LIke my mom, if she drinks green tea, she will have to go to restroom non-stop!

eat a lot of foods with salt but not too much because then its really bad for you

you shouldn't need to pee all the time.
go see a dr asap.
that was the 1st sign I had of a kidney infection.

you might have a medical problem or just drink too much water, pop, coffee...Go see your doc. God bless

aw, I know how you feel.
our classes last about...50 minutes? 55? something like that. then we have a 5 minute passing period (which is really hard to get a pee in if your next class is on the other side of the building and you have to go up to your locker first)
but yeah, I go at least once before I leave home in the morning, before 1st hour, between 1st and 2nd hour, between 2nd and 3rd hour (if I have time), between 3rd and 4th hour, between 4th and 5th hour, between lunch and 6th hour, between 6th and 7th hour, and before I go home.
my friends say that I have a problem =P
but sometimes it's just because I think about it. like, it'll be the passing period, and I'll think, okay, do I have to pee? no, I'm fine. then I'll think, well, it'll be a long time before I can go again, am I sure? then just thinking that will make me feel like I gotta go, even if it's not much.
just try not to think about it.
and I know one of my problems is that I drink like three cups of coffee every morning.
m tired.
so yeah, good luck!
