For want of better words, Comm was always very volatile, on your own don't create that, in fact it's quite the opposite and can help, because you are in control of your own space. It's when you don't have influences it becomes a problem which can make it seem as if living on your own is the problem, because you forget where the lines are. For me it's a mistake people often make when looking at the psychology of the situation, because they are judging by their own feelings of 'normality.'
Edit: so for example his drinking, he created an influence to break the habit with his charity event, some might remember I was always nagging Comm about his drinking, the charity thing helped draw a line.
