So I'm currently 16 and my mom got into an argument with me a couple months ago when I had my period .She called me "Whiny" and said all the pain was in my head. She also continued to call me selfish because i made "Everything about me."I had to go to school all week without the use of pain killers since it was "all in my head." So for the last couple of months, I've tried my best to show no signs of pain so my parents don't call me annoying, whiny, and selfish. At night, I just cry myself to sleep, no joke. The pain is just so horrible, and I can't do anything about it in front of my parents or else they'll probably send me to a therapist.
