Do I have a problem with talking to myself?

hi, i think you should talk to a therapist. it does sound like multiple personality disorder, you could look this up, but i am not a qualified person to give you a diagnosis or medical advice. and there are many disorders which appear like each other. if it is getting in the way of you living your life properly then you should seek help. but it is best not to panic at all and remember that the human experience comes in a variety of forms.
