I CANT DO ANYTHING!!!!!!!!!!

OMG being pregnant is so stressful you cant do anything. It seems like im always doing something wrong....Like i just found out i cant drink SWEET TEA like anybody who knows me knows i live for that ish...The doctor says i cant have it because its to much caffeine in it and it might effect the babys growth...Like WTF?!?!?!?! I wish i knew that BEFORE I  drank like 5 cups a day(being pregnant makes you thirsty lol)..Now im worried..............I HATE THE DOCTOR!
