No, it's grief. You used to have a partner to see every day who you closely identified with for 17 years. Now you don't. It feels like going around with a limb missing for a long time and I feel much of what I do for GAL still (7 months post bomb depending on how you want to count it) IS empty. If you've spent your entire adult life with a partner, it is a hard transition and it's not because you don't love yourself or fear entering the cosmic void or whatever. Your H's companionship is what you are used to on a gut and neurological level. Animals don't like being removed from their packs and isolated.
