((((((((((((stormyangels))))))))))))) I so understand what you mean. DID complicates things sometimes and it's hard for parts of the brain to know that someone is still safe without that connection, because of past experiences. My T does call and leave messages or emails during holidays and vacations, because she understands the chaos created by other parts of my brain. As my brain began to trust her and realize she was still her even after periods of time, parts needed that less. I'm so sorry your T has not offered that but I can also understand her need to separate from things.
If your T has not left yet, can you ask to borrow something of hers? A rock, picture, teddy bear or something similar can often help keep that connection until T returns.
I wish you the best while she is gone. Please PM me if you need extra support. I understand.
