The best I can explain it is "meh". Nothing is especially funny, or sad, or anything. It's not exactly numbness, and it passes. Some days I'll feel like nothing really gets "through" to me, and then the next day I'll feel like myself again. Like what wasn't funny the day before now is.  It's a weird feeling, and sometimes it bothers me and it makes me wonder if I lost a certain zest for life, but the next day I'll be normal again, or energetic or whatever other feeling and it's like nothing ever happened in the first place. 
Do y'all get what I mean?
