Echo PH it's going to take a long time to get through the reactions, the reminders, etc. That's why taking care of yourself is soooo important. It's gotta be tough with him feeling depressed and you going through all your panic - but hold onto yourself while your panic is running through your veins. Some things that help me - talking to friends, taking a warm bath and then cuddling with the cats, a good comedy, exercise, sunshine, flowers.
I've started buying myself flowers regularly - perhaps it's time for you to treat yourself as well. IT really lifts the mood!
