I certainly understand your pain and sadness, especially given all your events. You're right about getting the brain and the heart to cooperate. It's terrible to KNOW what you should do but be emotionally and psychologically unable to do it. My situation only began on New Year's Day, but it feels like a lifetime. [Side note: I posted the rundown of my situation last night as "New to separation and needing support." Read it if you're so inclined.]
I, too, am frightened of the unknown, but we really have no choice but to accept it and embrace it, right? Hugging you right back, and I'll be thinking about you. I wish a bright and beautiful future for you as well.
