not sure

I was working on some home work my t gave me and it set me in to a ****ed up state. Everytime I try to work with my little ones my mind explodes. nothing makes sense. I am in a fog and everything sounds too loud. I have body memries and fear. I feel like I am lost in this state. I eventually used ice to get out. it helped that and cold water in my face. but I am exhausted now. and I don't want to go out side or talk to people. I just don't want to be seen. This happens everytime. It feels like I will never come out of it but I know from past experiences that I eventually will but until than I am a mess. I don't like being out of control. I don't like feeling unreal

I can understand why you don't like that. It sounds very destabilizing for you.
Are you able to talk to your T about this? It might be a case of 'too much too soon'. It can be really helpful to develop a solid base of grounding skills before venturing into traumatic history and re-association work, just to ensure you have both the internal and external support necessary to maintain stability. If the homework triggers you to the point of feeling out of control it seems like a good sign that you're not quite ready for that work yet.
Are you able to raise this with your T?

I also used to get totally overwhelmed by littles. I hate it because it is so disorienting and confusing. My t would be ok with me stopping the homework if it was destabilizing me. In fact that would be what they want.
