ES, I get the sense that invalidation is a huge trigger for you, and that what I wrote earlier may have felt invalidating to you. I am truly sorry if that were the case. I know how awful it is to feel invalidated, and how impossible it can feel to cope with the triggered response to it.

You are valid. Your experiences are valid. Your emotional torment is real. Your pain is real. You have experienced abuse and you are still experiencing the effects of that trauma. It floors you. It wipes you out. it is so overwhelming for you that you cannot function. All of that is very, very real.
I personally cannot say to you "Yes, you have DID." Neither should anyone else here on this board. I sense your questioning and posts here are a search for validation. Sometimes I wonder if you feel if *we* thought you had DID then you would be validated enough to bring it up to your therapist. But we can't do that.

You need to talk to your therapist. You need to find a way.
