Mom is doing much better. She seems happier and is asking for food and water. She's more talkative and expresses her opinions more frequently. Things are definitely looking up with regards to mom.
Kat has started work as mom's caregiver and is really good at it. She's naturally compassionate and easy to talk to which makes for a perfect caregiver. She's able to take care of my mom's personal needs without my mom knowing which keeps both my mom and Kat happy which, leads to me being happy.
So, to summarize, Kat is back to work doing something that makes a difference and my mom is on the way to getting better which is a good start to some actual happiness.
Having my mom live with us is still taking some getting used to but, it's getting better.
We found out that the bank took ownership of the house because no one bought it at auction. This means that if my dad hadn't screwed us over by not getting us the location and time of the auction, my sister and I could have bought the house for the cost of the tax lien which was under $2000. We then could have sold it and paid off both of our debts and bought mom a small house out here for when she gets better. It's aggravating but, things could be worse so I'm still very grateful.
