Private Junk.

I used to be the one who can't be a demon during my period but now? I get mad almost everyday, I yell at everyone near me, I'm too busy messing up my mind and fill it up with many bad things and disadvantages, sitting here alone and having a conversation with my own mind, refusing people when I need them most, saying nothing but "I'm fine." even chocolates and ice cream can't heal the pain. Is it normal?
