Can they make you stop taking it ?

I’ve been on 75mg for abt 3 months now and I feel absolutely amazing. I’ve had anxiety my entire life so it is still hard because even tho my body doesn’t feel anxious my mind is still so used to certain comfort behaviors but therapy helps a lot. Me and my therapist think that this anxiety isn’t the result of anything actually happening and that it is a chemical imbalance. I’m almost 17 and I’ve never not had anxiety. There’s pictures of me as a very young child staring off into space biting my nails. I’m scared because I feel so good and I know the whole point of Zoloft is like to be on it for a year or so and try to re train the way your brain thinks, but you can’t fix a chemical imbalance. What if my doctor tries to make me go off of it? Is that a thing? I do not care about any of the side effects I feel so fucking good and I’m a whole new person and I desperately want to stay this way. I feel truly free. I no longer think and pre plan every single conversation and every action I make. I speak freely in class and I don’t care what others think. I talk so much now and learned I’m not an introvert. I feel so good.
