Actually probably just part of the process of grieving.
So sorry for your loss, Salamander.
(Is this a biker thread?) Nostalgia reference...
When one is dealing with grief, all things are normal, I got ticked off at my husband a few times after he passed. We were putting up hay in the barn with friends and he said he just wanted a break, sat down next to his truck, we finished loading the hay off the wagon into the barn, went to see him if he was feeling better, and being a nurse I could tell by his color he was dead, also being a nurse I did CPR on him until the ambulance came, I was yelling at him all the while doing CPR....for me that was normal, maybe not for someone else....Bless you and yours...
PS its been over 20 years and sometimes I still get mad at him......he was only 51. first and only heart attack....so its enjoy each day, you may not have a tomorrow.
