I hear you; I get that way too, especially when I'm extremely anxious about something. When I go to the dentist I have to get a chair near the restroom and I have to interrupt the procedure every twenty minutes to pee. Road trips do this to me too because I get anxious about not having a restroom nearby, so paradoxically I end up needing to use one every half-hour. It can be made much worse by my IBS, too; I don't know if this is something you have or not, but either way it's not terribly uncommon. It's like getting sweaty hands or dry mouth; your body just responds to anxiety this way. As long as your urine is clear you are probably doing fine. It won't hurt you to drink plenty of fluids to make sure, although I suggest water because the sugar in the Gatorade could actually make your anxiety worse if you're drinking a lot of it.
