My friend had a girlfriend, she was Chinese and he is mexican and white, so he called her his Chinese Take out. It was so cute the two of them, but she too had a battle with needs of meds that would make her calm, but both dabbled in illegal or recreational that to me destroyed both of them. It made them both crazy, but she would go for days without her meds and she would become Dr. Jekyl and Mr. Hide. Too much that he said that couldn't take it anymore and had to ask for time. Sadly enough the two are no longer but are indeed great friends. She can party and leave without taking her drugs and he can go on his way, as well. Long story short...meds/ and life style are key elements for these two, but with your story, it seems not so much the lack of discipline. I think that is indeed great that the two of you can still be friends, and I love your true virtue of knowing about those with medical needs and then the intolerance or apathy that many give because of it.
