Hi,
It's been 8 months now since Mom passed in January, since then, I have been in extreme TCB mode getting things done...some days are good and others are like an emotional train wreck when the grieving starts up...no rhyme or reason for it...it just happens...so many good memories. Joined a grief support group recently and that seems to give me some perspective that everybody grieves in their own way and time. Grieving is not easy.
If we didn't truly love the person we lost, we'd have no reason to grieve them. It is the price of love.
So keep doing what you're doing and over time you'll discover that it gets a little easier. Never completely goes away, but it does get easier.
