Since I was fourteen, I've been borderline hypoglemic and it really does affect your mood. I get depressed and pass out when my level drops to about fifty. Usually because I haven't been eating consistantly or the right things. But it is so hard! And I'm inspired by the changes you all have made with quitting smoking, eating right, probably starting new meds that affect your mind too. So just keep working at it, it will all work out.
