The last thing you want to do if you feel happy (even though these moments are so wonderful and rare) is let somebody else know you feel happy, because they will resent you for it. The thing is, people don't want to see you happy. They want to see you miserable, or at the very least, whining about some small and insignificant thing. Like they do.
I'll tell you what they really want. They want to see you in pain. Only then will they be satisfied.
