Life is not supposed to be great. Even for people with no "issues" to deal with, it's still not easy. My life's been total hell because of my SA & up until a year ago I was very cose to killing myself. I nearly did. Luckily, I didn't, though & have since been receiving help.
If you haven't gotten any help, you really need to. Killing yourself is not the way to go. Believe me.
