Least, I've been suffering from it since I was very young. I'm sure much of it is related to the dysfunction, abuse, etc. I grew up with. So I am pretty certain that some at least of my episodic depression has a lot to do with my family of origin. No one would believe how cruel they are, my sisters in particular, but then they are both sick and addicts. So I have to see things as they really are not as they would like me to be, which my sisters would love me to be down and out, but I won't be. The sick man prayer is a blessing for me when I have to be around them. Other things cause depression, maybe I was wired for it. I wish I had the answers. This thing with my sisters hurt and is infuriating. I really intensely dislike both of them, but I wish them no harm. Oh well. One of my lessons I guess.
