Quite a few parallels between you and I 29. My wife and I were also married on 8/22/20 (my 3rd, her 2nd). My mom got very sick the last week of December and on January 1st she was diagnosed with Covid. We lost her on January 8th. At the same time as she was getting sick my wife's parents both came down with Covid. Mother in law pulled through the Covid just fine, but her dementia really ramped up. Father in law was touch and go, but he is going to make it now.
The big challenge now is transitioning mother in law back home this week. She had to go into a rehab facility for her dementia and to allow father in law enough time to get some strength back. She comes home on Wednesday and on Thursday my wife and I will be inbound to Phoenix to help with the transition and get a lay of the land for what future services might be needed for her.
My condolences to you and your family for your loss.
