I don't think generalizations are a good thing for anyone, so I would never make a blanket statement that says all people should get off of meds.
I think you need to re-evaluate the effectiveness of your treatment and recovery from time to time, and a part of that may be to decide -- in conjunction with your care provider -- that it's time to discontinue medications.
I've seen people with the diagnoses you mention get off of their meds and lead good lives, and I've seen others who've tried and it not work out so well. The key is to find what works best for you and to follow that.
Best,
