Vertigo. a very serious question for very serious answers, im really getting scared.?

im 26 years old and since i became pregnant ive been getting bouts of vertigo here and there for the last 4 years. theyve increasingly become worse. ive had vertigo now for the past 2 and a half weeks and its not just vertigo anymore, its a constant state of being unbalanced now even when im not spinning. its effecting my life a lot. i suffer with depression and anxiety as well and have been on lexapro and xanax for the past 10 months. i should meantion that i was diagnosed with a benign pituitary tumor when i was 16, but i hope that people reading this will evaluate all other angels as well. i have an appt to see my doc on the 12th, (SO PLEASE DONT JUST TELL ME TO GO) but im really getting scared now. im a mom and its effecting my life daily. even though my last bout was only a week about a month ago, i still cant remember the last time i felt completely normal (by normal i mean with out a haze). this is very serious for me and i hope all that answer will take my emotions into account. thank you for your time and answers. please help if you can. btw: my blood pressure and everything is perfect, i also had my gall bladder out this last march if that helps. thanks again.
