It's possible that you may find it therapeutic, OP.
I lost both my parents in less than a year. Both had dementia. When my DM died, the council gave me 2 weeks to clear the house. DPs were hoarders, and the house was filled to the gunwhales with stuff. It seemed impossible, but I had no choice, I had to crack on. My DB has MH issues and was too unwell to help.
For the first few days, the place was in such a state so that I couldn't even stay overnight, plus the boiler was broken so no heating or hot water initially. It was a 4-hour drive each way, because of road works. I was in a dreadful state, grief-stricken, exhausted, angry, couldn't stop crying, couldn't sleep, couldn't eat.
I spent 2 solid weeks clearing that house, registering the death and arranging the funeral. One w/end my mate and her BF came and helped for 2 days, apart from that, I did it all myself.
But when it was finally done, and I was heading back down the motorway for the last time, I got a strange feeling somewhere between relief and elation. It was amazing. I was still grieving, but in much more manageable way. It lasted a few weeks, iirc.
I think the whole process gave me some closure.
