Blondes I am so sorry for your loss.
Wrt staying or moving from your house, let me share this with you:
10 years ago my grandad died from a heart attack infront of me, my nan and my ds at their home.
My nan never really got over it (that sounds flippant but its not meant in that way) and she struggled with depression for several years.
5 years ago she decided, after a lot of heartache to sell up and move nearer to my dad, her only child.
Once the sale had gone through I think she realised she couldn't leave the home she shared with my grandad and where be died. She must have felt there was no way out if the sale and that she didn't want to leave without him. She committed suicide at home.
I identified her there the next day.
The house sale still went through and we had to clear it in 3 weeks. I spent a lot of time in that 3 weeks at the place she died. There was, and probably still is, evidence of what she did.
With my dad not nearby, I dealt with everything- paperwork, house, inquest, we did the funeral together. It's bloody horrible isn't it?
I sometimes drive and sit outside het house wishing I could go in and just be there.
I don't think your mad for staying at home. I took comfort from being in her house, being near her. (i'm not suggesting you're like my nan btw, more comparing you to my situation)
Let yourself grieve. Roll with whatever you need to do. 5 years down the line and I still won't let it happen, I'm too scared how much it will hurt. But you sound like a brave woman, be kind to yourself x
