I used to think everyone has to cry for a reason, but I noticed because I am diagnosed with bipolar, that I cry for no reason at all. The thing I picked up on is that I even noticed when my moods are changing into sadness. It's something that happens little by little and than the depression mood will hit where I begin looking at the world differently. Good thing I'm on medication now and my moods are doing a lot better than before, but I noticed where I will cry for no reason at all. Anyone relate?
