Born to grumble, born to cry,
Every day, at work or at school, you encounter me.
Help does not come, you must suffer through my cause.
Love and hate, they say are a pair, though I and happiness, are we not?
BIG HINT:
I have shown the answer 2 times already, use the riddle to only confirm it.
Another hint:
Meh, I'll add this later. Ugh, pls don't take this out.
The 3rd hint:
Agh, the BIG HINT was supposed to to say THE ANSWER IS ON THE SCREEN NOT ONCE, BUT TWICE.
