Exhausted and worried

My daughter is going through hell and it breaks my heart. She has disocciated twice this week and had two panic attacks. Today I went out for a while and when I came home she was in the shower. We spoke briefly, then she fell asleep with a towel over her pillow for her wet hair. She has been unwell with a sinus infection. She woke out a couple of hours later and freaked out (had a panic attack, then afterwards tears and negativity) because she had no memory of the shower and a text she had sent her friend as she must have spent a few hours in a dissociated state. I spent a long time reassuring her and listening but everything I said was wrong. I am exhausted and dont know how to help her when shes like this. She wants me by her side but seems aggravated by everything I say. If I go to leave the room she says I dont care about her. Has anyone had similar experiences with their loved one?
