it sounds to me like she wants to add another T, someone who specializes in DID, but still keep seeing you herself, too. I can definitely understand how it feels to have those abandonment & rejection triggers hit. It feels like crap! I'm sorry.

eta: just wanted to let you know, I can also relate to the feeling of being too high maintenance for everyone, that nobody will stay around me or in my life because it's too much work, that I don't have the right to ask for anything or the right to have needs. I know how ****** that feels, and I hope you can know on some level that it IS ok for you to have needs and to ask for and receive help.
