Acted crazy, now he's ignoring me?

I acted crazy toward the guy I was seeing . Very bipolar one minute I was nice the other I was acting like a psycho girlfriend. And I tried to apologize because my hormones were messed up by birth control. I sent him and email apologizing then text but no response.. I'm really disappointed in myself . It's not because I want him back it's because I wasn't a nice person..
