I feel very bad for 3 days every month, in these three days, I can't see any hope in life, I feel everything is against me, and don't want to do anything. I was very confused about this in the beginning. Then I realize it is very common, so I don't worry about anymore. Just treat it as usual thing.
I mean I feel bad these days, this is why I say bad words about you, my friend, will you forgive me?
