A while back I joined a guild in a game I play. It was a relatively small and tight-nit guild, so we all became good friends. Eventually a most people quit or became inactive, so I decided to leave in order to find a more active setting.
Unfortunately, this made one guild member lose her mind. She disappeared from the game for over a year, deleted everyone from her friends lists, and left the old guild. I know she has been back recently, and I talked to her briefly this summer. From what I gathered, my leaving sent her spiraling into depression (Which was pre-existing, but this sent her over the edge), made her reclusive for the time she was gone, among other things that aren't relevant here. I also said some things this summer that I meant as sincere and true, but may (and probably did) have come off as rude, snide or condescending.
So my question for you guys is should I try to make amends or just let bygones be bygones and avoid her? It may not sound like it from the rest of the post, but I miss having her around as a friend. It's like losing a really good friend you had for a number of years who disappeared out of the blue.
