why did these happened to me?

it's not right to regret what had happened in our life but i wanna still regret it.. i've make lots of mistakes in my life.. running away is not the right choice.. but can i do so? i feel like i wanna go to a place that no one knows anything about myself.. start a new life.. making new friends.. feel new environments.. we can't back to our past.. if we can, i'm the first one to do so.. i wanna fix my life before.. start appreciating education and enjoy life without making any big problems.. i wanna be an architect since in primary school.. i love to design.. but i don't know why i'm taking different course in university.. argh!! tension pulak tibe2.. =.=''
