Fuzzy,
What has helped you in the past? I get that your options are limited, but you are loved and needed.
My t has had me doing a visualization where I thank the emotion that has overwhelmed me and then remind that emotion that I am now in charge. It is a little simplistic, but seems to be effective in my case.
I hope this helps a little bit. I almost feel foolish saying anything, but I feel a bit more steady... even after a long, emotional session yesterday.
