Four years is a long time to do anything. For what we actually make there has to be more than just the money here. I too have made lots of friends and met quite a few of them in person. Who knows where we will all be in another four years, but I hope those are better times for the world. Sorry to hear your girlfriend lost a friend. That's always tough, but it doesn't help when you can't be with people as much.
Stay strong and stay well.
