Gordie just made an awesome comment. You should be proud of yourself. The AC is a stressor, like your birthday is, her birthday, kids' birthdays, anniversaries, Xmass, halloween, and a ton of other dates. They are painful, because they remind you of things passed. The solution is to make new memories, and new dates yourself, for yourself and your kids. I will never forget how I taught my kids to swim, all by myself, how I taught them how to ride a bike, all by myself, and a ton of other things I did, all by myself. The pain of these dates slowly is slowly fading and new memories are flourishing.
