GIMA, allow yourself grief, even if it makes no sense to you. Feelings are complicated. You have an entire life behind you now to grieve, and also for the unknown future for you and your kids. I'm so sorry you are going through this. One day at a time. Feelings are irrational and may sneak up to nab us. But if you allow space for them, they will shift quicker.
Sound wisdom for all of us. Thanks.
"Always go straight forward, and if you meet the devil, cut him in two and go between the pieces." - William Sturgis, clipper ship captain, 1830's.
