Depressed. I want my life back. help me!

I'm an engineering student. But i have lots of problems with my personal and also educational life. I thought of giving up and to commit suicide, still i want to live my life. For that i need hope. I have been so hopeless that whatever i say my teachers think I'm doing drama and all other people think the same. My boyfriend stays with me because i need help,he never speaks about anything i want.. He wants to have physical contact and tells me be practical,stop being like something has happened. But my hopes shattered all the way .i don't wanna stay at clg where everyone thinks I'm crazy.. I just want to live my life the way i want .i don't wanna live my life for others. I tried to do so, nobody recognized it.. I don't want anyone to recognize.. But atleast i want somebody to appreciate.. I live my life alone at Bangalore. I want my life back. Help me
