birth control
"I went on this pill when I got into my first serious relationship.  I've tried other birth control pills before and had to go off of them because of weight gain. When I finally got back on the pills, I thought it was great because my periods were always regular, I had no weight gain, and my skin was flawless.  But, after being on it for 6 months now I'm realizing that this pill is the reason for my poor mental health.  I went from being happy and satisfied with my life, to being an actual crazy person.  I started lashing out at the people I loved as the months progressed. I would have the worst mood swings of my life.  I would be happy and laughing, and the next minute I was in tears.  It turned me into an angry person that I didn't know."
