My father has an undiagnosed mental disorder. I’m just asking advice from experience and not a diagnoses. 
I used to think my dad had dementia or Alzheimer’s but when I realized his mental condition wasn’t getting worse as they do in these disorders, I know it must be something else. 

My dad has a hard past. He has had ECT done in the old days when it was much different. My dad also have an OD from an antidepressant but never went to the hospital. Every since that day, he ya been different. He has paranoia and the main thing I’m asking is, whenever I move an item around that he placed in a certain spot, he gets really upset. Is this OCD? Everything needs to be in a certain spot! I don’t understand it. And he also tells me not to do certain things because when believes something bad will happen. 


I also noticed that he has good days and bad days. On the bad days, he seems in his own world, zoned out. And on the good days, it’s easier to talk to him without having to repeat yourself. I also know he hears and sees things but he won’t admit it. He sees shadows that aren’t there. It was worse when his life was in shambles, he felt shocks or seen shocks. I think this could be schizophrenia. 


If he didn’t have kids, he would have been homeless due to his irresponsibility. He makes decisions where he doesn’t really think about the future. I guess some of these things have been that way his whole life. 

If anyone has any ideas or just even advice so I can understand better, that would be awesome. Thanks in advance.
