I'm very sorry for you ,the loss of you dad and the tragedy this horrible desease has brought to your door. Hopefully people who are not familiar with schizophrenia will take the time to understand the devastating effect this difficult to treat illness can and does have on so many families. Anyone who would make any unkind judgements or assumptions about any member  of your family should go to Youtube and watch this short video of Anderson Cooper attempting to fuction for a short time in a simulater that shows some of what a schizophrenic  has to deal with all of the time unless they are medicated with medication that often leaves them with other physical and mental health  issues. I am so sorry for all of you, your dad was a very nice man. https://youtu.be/yL9UJVtgPZY
