Feeling like a failure

Im pissed off,angry, upset,hormonal and wanting to eat all the greasy shit i can get my hands on AND in pain (not the greatest of combination! !) So we spend our teenage years trying not to get pregnant and the other half desperately trying too. I feel like a failure when my af arrives like i cant even get that right. Guarantee by tomorrow im not even gunna care and ill be back to my normal self. Hormones are fucked i hate them 😢😃😄😊😠😢😀😣😍
