DDNOS or something else

I was diagnosed with DDNOS in the early to 2000s. I dont remember why or my sessions just my diagnosis. Anyway, I was like nah I dont have it and things were relatively calm. About 3 months I realized I hear chatter. I am 42 years of age. My old psychologist doesnt remember anything helpful about my case. My chatter which just sounds like thoughts say weird things like- I am going to take you to Greenbriar (never heard of it) I am going to cut your wrists (referring to myself but I dint really want to) we need to go get some water (who is we) my stomach hurts ( when it didnt) what is a black hole ( i already know) f tuna! (Random nonsense at 12 in the morning) shhh mommy (no one was around) and tons of other stuff. I dont lose time during any of this. Also they just sound like thoughts. I dont hear but one person in my head and that is me thinking. What is going on?
