I hope you are feeling a bit better. Reading your post actually helped me. I've been through the angry with everyone and everything mode. It's horrible.
Keeping busy, busy, busy helped in the beginning. I got on my hands and knees and washed the floors in my living room, dining room and kitchen. Folded a load of laundry and am now here. So, I had that kind of day too.
I think EndGame has it. If I am angry I am usually afraid of something. It just sometimes takes a while to figure out what I'm afraid of but I get there. Hang in there. Post here.
