I think a lot about this. I have come out of a really severe depression. While it is great that I am no longer in that really dark state I now wonder is this as good as it gets. Because I'm not miserable but I'm not happy either. I just exist. I get up in the morning thinking "oh boy I have to do this again" and do my best just to get through the day until I can go to sleep at the end of the day. If this is as good as it gets is it worth it?
