I have some experience with DID cuz I was misdiagnosed with it. Some things psychiatrists look for is if you show up differently in sessions, voice/handwriting changes, confusion with the IFS or it frustrates you, and regular dissociation. Turns out I just was in a psychotic bipolar episode and when they told me I had DID I played the part because I was convinced too
I’m struggling with this too😭 Sometimes I wonder if I have DID but my altars are just really good at staying hidden. I do IFS and it has been so confusing cause I’ll wonder “is this a part I’m just really integrated with or a whole other person?” (I’m sorry if you don’t know what this means😵💫)
