<<I just keep hearing "ACTUAL" reasons to why I am sad... the reason I so highly think it's combined with biological things is because I sometimes get very sad for very stupid things. I can know myself that it is nothing to be sad of be still I can't help it..>>

It's definitely biology, sort of by definition. Sadness is an emotion, and science has proven that we have emotions even before we cognitively know why. Just as dreaming is brain activity, just activity, but our Frontal Cortex tries to create a story, or reason for that activity - it makes total sense that if (as people with Depression) our brains fire "sadness" activity, our minds would create a "reason", even if none really exists.

I'm definitely coming out of this current funk. Chicken and egg? As I'd shared, this board has helped me get motivated a bit, and more importantly ACCEPT MY DISEASE. So when today, out of the blue, I got called for a last minute acting audition (I'm an actor), I just ACCEPTED that "I'm not ready", etc. etc. I decided to just be me, and not apologize for or overcompensate by trying to hard.

I got the part, and that, of course, is motivating to make tomorrow another day of healthy behavior. I'm actually making a list: "Things I could do that MIGHT be fun or make me feel good", and I'm going to just start checking them off.
