I wanna die ! Please help !?

First off all I have no desire to live my life ! I have none in this world ! my parents ped 2 yrs ago ! no relatives I have .i am 25 yrs male ! In the life I had 4 crushes : Rukshana , Dimpy , Liza and Dolly . Where Rukshana was a Muslim and i was just 15 when I had the crush ! My parents were alive and hearing my crush they laughed and said that she was an idiot and It was the most idiot girl in the cl and I was the topper and our inter religious underaged love was illigal ! Later when I moved to engineering college met the others but Liza and Dimpy never looked at me at all ! The girl I love was Dolly who also loved me ! After my parent's death I was like dead but she was with me at every step ! but she will not get married with another man a week later and she and her mother rejected me as I am jobless and poor although being an engineering graduate ! Now I have none in this world ! Will I die for grief ?
