I have a coffee problem!!!!!!!!?

ok, so i'm 15 and i normally don't drink coffee. I've only had coffee drinks like 7 times. I do drink soda with caffeine in it. So this morning, I woke up super early cause i couldn't sleep and i still had to go to school so i asked my mom to take me to starbucks to get a coffee so i could wake up. So i ordered a tall mocha frappucino and drank it all. it did help me wake up but the whole day i felt kinda off. like when i tried to talk, words came out slightly slower than usual and i just didn't feel right. i didn't feel bad or jittery, just not normal. and then like and hour after drinking the coffee i had to pee super badly. like so badly it was hurting my bladder and when i did pee it came out really fast and a lot. so as the day went on, i went pee like that about 6 more times and ea. time it felt the same and it was like suddenly i had to pee badly, not like oh, now i kinda have to pee and then fifteen min later like ok, now i really have to pee. it came suddenly. then later in the day i started to get a small stomach ache like in my lower stomach. maybe my bladder. the ache went away after like 30 min. and i've felt bloated ever since the stomach ache. this has never happened before! its super wierd! its not like i never drink caffeine. and i did have breakfast before having the coffee. help!!!
