ok, I think I have solved this question on my own somewhat, maybe not completely as far as what things are called (terms used). I was triggered by something small 2 weeks ago but it did trigger a big reaction because it was something that triggered me based on abandonment issues (which is significant for me, long story short). I did withdraw, I did have the usual 4 day thing happen, my personality did go away and was replaced by negative and painful emotions, but after this I think I started having depersonalization. My symptoms on this match what it says on wikipedia for this. So I think withdrawal is not often in descriptions of dissociation but it is connected and can lead into forms of it. I was reading something by an early psychologist from about 100 years ago and he was describing withdrawal going into dissociation as being part of the dissociation process, so it's not that withdrawal is separate, and it's not that it is dissociation, it's that it can be connected, or lead into it. Actually I've seen info on psychologists websites that show that they think it's part of it. So it's a language thing, it's an interpretive thing, It's however you want to view things. That's what I think now based on what just happened. I don't usually get the depersonalization part but it shows me that the other stuff can appear without it. So it's up to interpretation if someone wants to think withdrawal is part of disociation. Descriptions in modern times seem to leave the withdrawal part out.
