on days when I feel like im 'going to crack' or am just having a rough day I try to meditate or I reach out to my support groups via face book for advise or simple comforting words. also, knowing that it's ok to have those days, and days where I need to be away from the day to day and the people day to day. self care is about taking time for yourself sometimes, so you don't crack, or lash out, or lash inwards.
also, I plan. I plan my future, maybe several futures, that mental exercise and immersion provides both a possible path forward and a distraction from what ever is eating at me, be it work, queer issues, or life in general.
I couldn't answer yesterday because I was having a rough day gender wise myself.
hope this helps
