Ramadan Sect - How does one stop being so angry?

I have never felt so angry in my entire life. I just wonder why is there so much injust in this world. The more I learn about this place, the more angry I get. I'm tired of hearing the suffering of innocent people; the way people are killed mercilessly, the way people are so inhumanely towards each other...arghhh. I think I have lost trust and faith in almost all people. Random things really are getting to me. Yesterday my mum was complaining about something...going on about what my future husband and in-laws would think...then I was like "WTF, is he going to marry me depending on the way I fold a frikkin samosa?" Is this what marriage has become? You get married depending on the way you fold a samosa? Then I vowed to never marry if all men only care about things like this.
