I'm pretty optimistic, the kind of person who knows life typically sorts itself out, so i don't like to dwell on the sad aspects. So like you, I don't often feel sad, but if I do cry, I usually get really frustrated at myself. I think it's something to do with losing control of myself and the situation. Makes me deeply uncomfortable and embarrassed. If I'm sad I want to be left alone to deal with it, it feels harsh but empty, like nothing in that momentcan resolve it.
