My father had a stroke about 10 years ago that left him paralyzed on his right side. He has always had substance abuse issues stemming from a lifetime of anxiety and bipolar struggles, but now he is refusing to take his Wellbutrin, and is drinking liquor. He also has a medical marijuana card and smokes all day. He is short tempered and belligerent now that he is off of the Wellbutrin, which is damaging all of his relationships. He seems to have given up, and doesn't care about consequences. His stroke also affected his ability to discern cause and effect relationships.
One of his doctors advised him that when he is feeling angry he should remove himself from the situation. This leads him to get in the car to go for long drives, often with compromised sobriety, often getting lost.
At this point his significant other is at the end of her rope, and the relationship is badly damaged. I live 4.5 hours away, and try to get there as often as possible to give his SO a break, but it's not enough. My younger brother lives closer(1hr), but is not in a great position to spend a lot of time there due to work. I think I need to find a place for him to live, as staying at the house with her is NOT working, and staying with me is not an option. I am way out of my league here, and possibly too emotionally close (read: angry and confused) to make good decisions about the future. I honestly don't even know where to start.
