One thing no ones knows about me

I never really knew it, but along the way I found out I have really bad mood swings. I guess you can say I’m Bipolar. I get very mad, and I blame the person closes to me(it’s always my mom) They seem to calm when I’m happy, but they always find their way back. It’s not really safe, I get really angry and after I cry and I just don’t feel like looking at people or even being touched by anyone.
