I’m also sorry to learn of this news. Very sad. If you want to talk about it, shoot me an email and I’ll talk to you about it. If you want.
I recently lost my father last year to lifelong addiction to alcohol. So my sister and I had to do all his arrangements and split his belongings and all of that, as he had no will. These things usually come out of nowhere, but it sounds like you had a least a little time to plan for this?
