Let me just explain real quick:

I have very intense anxiety about certain subjects, but I am not diagnosed with any anxiety disorder. (I am thinking about trying to get diagnosed soon) One of the subjects that makes me have crippling anxiety (not just fear) is driving, especially under weather. So much as one tiny cloud that with a 0% chance of rain, I am on the verge of tears. I am 14, so I am obviously not old enough to drive, just being in the car is torture.

I have plans to go to an event on Sunday (2 days from now) which is about 2 hours from where I am currently staying. There is a chance of thunderstorms while driving, and while being there. 

I SO desperately want to go, however, I can't even imagine going with even a chance of rain. Does anyone have any advice? Should I ask my parents for pills? Is it too late to get them? Should I try to get through it? I will take any and all advice to help me get through this. Please
