ChatGPT’s fixation on my past conversations has made it borderline unusable

In the past, I feel like I could count on coming to ChatGPT and, generally speaking, get the “best“ answer when I asked a question or wanted to explore an idea. for some time now, this is no longer the case. At some point, chat became so obsessed with everything it knows about me that it seems to be no longer capable of providing the best answer. it just provides answers that relate to things I’ve mentioned in the past, answers that include interests I’ve told it about, answers that continue/build on previous ideas that I’ve explored, etc.
