I am really struggling with freeze states and wonder if anyone has advice...

My freeze states are so bad they last hours, a whole day sometimes. I get "stuck" and can't move or make decisions. I'll make attempts to get myself out of it, but it's as though they all hit a wall. It even feels like I'm determined to stay frozen, even though I'm stressed by it, tired, bored, frustrated, maybe anxious, and deeply self-loathing. I try to get myself to start something that I *know* will get me up, but I can't. There might be something positive awaiting me, but I can't move. It takes me a long time to even realise I have frozen and I can't work out why it happens. I try to make plans to avoid the worst areas, like waking up and just never leaving bed, but my plans don't work because in the moment I freeze instead of following them. One thing that seems to get me out is if someone just comes and says hi to me in person, and then suddenly the blocks are gone. I remember lying in bed for hours trying to persuade myself to get up to go help my mother out. I couldn't move. She said hi to me from the other room and I jumped out of bed easily.

This is driving me crazy. I have no agency or understanding. My therapist suggests it happens because I secretly don't want to do things, but I can't understand it that way, because I feel so bad when or after (depends how numb it's making me) it happens. I don't understand why I wouldn't want to even do a basic thing like make myself more comfortable, since being in the same position all day is painful, let alone why I wouldn't want to do things that improve my life. If things are scary or hard then that makes sense, but then why wouldn't I understand what situation had triggered this to happen?

Has anyone found a way to deal with this kind of issue?
