(((((((((((((Notonlyme))))))))))))))
I'm so sorry. So often when I want to disappear, my brain is able to handle whatever is going on and I stay and then when I want to stay present, bam, I'm gone. Sometimes there doesn't seem to be a rhyme or reason to it.
I'm so sorry that things are so hard right now. There are some posts here about grounding that might help. I think they might be in the ptsd forum in the paper clip area (or whatever it's called)? Maybe someone else will know and can post a link.
Please take good care of yourself during this time and let us know how we can support you.
