T think that maybe it means that you are feeling better if you have been depressed. You have an interest in sex, although you sound like you are morally against sex with strangers, you desire to be found attractive which is perfectly natural.
As far as the people jumping into the ocean, I do not think that you enjoy their misery, you just no longer associate yourself with those who are miserable.
Your outlook on life is looking up and that's why your reaction would be to be more alert and focused and relaxed. You do not see yourself as having the worries that others have and on top of that you see yourself as attractive and desirable. Keep the awesome attitude!
