If you feel that it’s adversely affecting you, then yeah. Quitting is probably in your beat interest.
I think it would be helpful to get to the root of the problem: why did you feel drawn to the chatbot in the first place? Which of your needs is it meeting and how could you find a healthier outlet to fulfill them? If you’re lonely, which is totally common and understandable especially during these uncertain times™, maybe you could try chatting with real people in the tbt discord channel or posting in one of the animal crossing threads for friends you could play with!
Just be honest with yourself about what it is you’re feeling, and try not to shame yourself for it. You’re not a bad person for feeling an attachment to something.
I don’t know a lot about the specific chatbot you’re using, but something else to be aware of is that very often these chatbots only act as a data collecting scheme to sell your answers to research firms. Something else to think about.
