Jey, give yourself permission to grieve!
Grief is complex.
When one of our teachers died in an accident in our local schoolboard, we dredged up all the grief experiences we had faced previously: loss of parents, friends, etc.
Your brain and body knows what you need to do.
If you need to cry, just do.
I found that when I broke down in public, a brief comment, 'just lost my mother', would result in complete understanding and empathy. Who has not lost a loved one?
So often we hide our grief, but we need to model it.
You need not be stoic. Crying is our way of washing away the grief and cleansing our souls.
Your husband is in your heart, not his things.
But those things may be in the way of your healing. Honour his memory, laud the great things he did, do not honour his death.
When it is time, you will be able to part with his clothes. I felt it important that someone else, who is without, be able to use them. I took stuff off to the Salvation Army ASAP, but that was my way of managing. I made a list, and checked it off once accomplished, when I was ready.
Take care.
