I kept many arrears in my semesters and feeling so depressed...Can anyone help me?? I feel like dying!?

I am studying BE ECE first year.... I have kept many arrears in my first semester. I thought I could clear all those papers in second semester but i could not make it... Instead I kept some more arrears in second semester. I tried a lot to do well in exam but I could not make it. I am losing all of my concentration and nothing stays in my mind in exam hall. I don't know what to do. I am feeling so depressed. I feel like dying...I cant take this. I studied well but nothing stays in my mind while writing the exam.Though I study well I cant write my exam well. All peoples were disgracing me and making fun of me. what can I do now?Please help me!!!!!!!!
