I am feeling lonely..I want a beautiful girl of my age to love me! What do you think?

I am male—21 years of age. I am a single child. My parents love me very much. My aunts also love me very much. But I feel lonely and depressed as I don’t have a sister/ girlfriend..I want a girl of my age to love me very much..She should be there for me everytime and should support me always..I want to talk with the girl..I want to tell her secrets and entertain and delight her..I want to love her and have physical relationship..If I marry soon I might get a wife..but still I want a sister-type of girl too..I loved my cousin very much..she got married and she left..My other cousin has come to visit me from US to India..I have a crush on her..But people say she’s like a sister..but she does not like me a lot..God!! I don’t know if I want a girl in a relationship like a sister, girlfriend or a wife..I want all 3 types in 1 girl..I feel very depressed and sad..I am crying..sob!! Help me someone..I am Indian..am handsome..I am creative..am a dreamer..I am stuck in a mess..I have to create imaginary angels to talk with..but I am not satisfied..I am an adult..I feel attracted to girls on the street..I am afraid..I am lonely..Should I pray?? I know that it won’t help..I must have done a terrible sin to a woman in my last life..that’s why I am suffering..I am traveling in circles in search of sisters and lovers and in the process I am finally falling down in the same place losing hope..
