<human>: Can you provide a brief overview of the text?

My father was drinking tonight. He is practically a schizophrenic drunk. He and my mother have been having problems, many of them are because of his drinking. THis is rely hard for me to write right now because he is actually being well unpredictable right now. I need help/advice on what to do right now, and later i need advice on later. So ill try to give you some info on whats going on. i got home from work and my father wasn't home. My mother thought he was with me. which is pretty stupid. I checked the house then went down to the bar. i found him walking home from the bar but he didn't want a ride. He got home and started fighting with my mother, nothing overly aggressive. My mother had said the next time he drinks she is calling his sister to pick him up so he can stay with her. this was the start of the whole fight. So basically my father was simply drunk walked in and my mom called his sister starting an argument causing him to walk out of the house and down the street. Why does my father walk every where? it isn't because he had been drinking but he has a horrible vision impairment which practically blinds him, worse it causes him intense pain 24/7. His drinking has picked up sense his eye problem started. So my dad is walking down the street and I chased after him. I will elaborate later. After walking with him for two hours through the ghetto at 12am on a saturday, I got him back home. he is pissed at me now too. I have way more to elaborate and i don't exactly know what to ask for help. He literally wants to run away should I stop him? 
There is so much more to the story and more ways i need help with it but seeing as how i am in this event right now this is the best i can do.
<bot>: my handy cap father is having a mental break down right now. he wants to run away. Should i let him?
