You are equating depression to how you feel briefly after a loss? That is not depression. I will do a little Dr. Phil on you. You are a psychotic, sociopath yourself who is far out of touch with reality. I say this because I honestly believe you believe what you are saying. You lack empathy and it is not your fault, you are yourself sick but don't know it.
And no, people like you never kill themselves they are too self centered and selfish. Even your solution to un-depressed as you call it, is to do something self serving. Why not, you are the only thing that matters in this world. It's how you are wired and you can't understand how another may feel different, nor do I think you really care.
