Wish someone had diagnosed my dad's brain

If you try to get to know him, try to spend time with him, he WILL find a way to be a rude ba.s.tar.d till you leave him alone.

Months after no-contact, he called me one day and complained about his children never spending time with him. He was all confused and erratic and extremely depressed. He said his children were egotistical and mean and selfish creatures who have a political agenda against him.

Nothing much different than what he believes in when he's not confused. He just expressed it in a manner significantly more crude than before.

He got sick soon after.

Now that I'm back home, I tried a few times to spend time with him, only to find him scornful and condescending at certain times, and indifferent and irritated at others.

So then obviously I stopped spending time with him.

I don't see him now. At all. Only if he calls me for something.
