Are you by any chance a reader? The book 'On Grief and Grieving' is a classic. Perhaps it might be of some use to you?

It helped me a great deal years ago after suffering several significant losses in a short period of time. I had eventually ended up in a place of feeling rather numb, just because it was all too much to process.

I'm so sorry for what you have gone through. It is a tremendous amount. Well more than anyone should have to deal with at one time.

You are always welcome to post your thoughts and feelings here.

Sending hugs your way.
