No regrets either, that it took a life-threatening illness for me to understand just how toxic my relationships were. When waking up everyday is an awesome surprise, regrets are just wasted head-space.
Kinda like when I'm walking my big-ass German Shepherd and see a stranger coming toward us on the sidewalk and, without a word, nod or smile, I simply cross the street. I feel nothing for the stranger. My only thought is protecting my buddy, who gives me nothing but unconditional love.
Done is a journey but, damn, when you get there it's a great place to be!
