New pill...

I started taking a new pill after years of taking the same one. My Obgyn was concerned about the fact that my period was so heavy. But this new pill is killing me. I've never exprenced so many emotions at one time. Also my period has gotten to a point where I only get it for a couple of hours. I had some horrible blurry vision and apparently that was the pill too. I'm so frustrated that I just threw away all the pills.... I don't really have a question I'm just really upset about all of this.
