god bless. similar situations exist in my family. found on both sides of my family (not drug related) and it has impacted my family greatly. It's best to try and understand the situation, and not what is going on in their head. My uncle has severe bipolar disorder and his ups and downs can last up to a year. He exhibits similar behavior. We cherish the times we have with him when he is stable and remember those times when he is not (the pills keep him in line, when he takes them). God Bless and I still pray he is ok.
