Dear Bobby,
That's great about Luc being in a good place.
Maybe in lots of ways you two were good for each other even though his stay with you was very short.

One of the ways I force myself to get out is to tell myself that I can come home at any time. I allow myself to leave as soon as I get there or even in the middle of the event. It's sort of a trick I play with myself to force myself to attend. Sometimes I stay.
Other times, I follow my rules and leave when I need to. Nobody remembers later that I walked out. I'm plenty self-conscious, but I am ok about getting up to go one minute past the point I am uncomfortable and need to be back in my own space.

M.
