Depressed, and almost suicidal.?

Ever since i was enrolled in secong grade people have always thought i was gay, and i hate it. I never really had a dad, and my brother wasn't aroud most of the time. So i never had a male influence. All i had was my mom, and i guess i always copied her. I never really liked guys, they always made such fun at me. And ive been trying to break the mold, but nothing seems to work. THis GAY thing is pushing me towards the brink of suicide,i hate going to school, nothing inspires me to wake up in the morning, my family is breaking apart, and i hate all my friends. My life is filled with empty promises. And you know what people are always telling me to cheer up and smile. SMILE ABOUT ***** WHAT? THERE IS NOTHING IN MY LIFE THAT MAKES ME HAPPY, AND SOMEONE TELLING ME THAT THERE ARE REALLY EVIL SPIRITS AROUND ME AND THAT MY DECEASED BROTHER, OF WHOM I WISH WAS AROUND TO GIVE ME SOME HOPE, WOULD NEVER GET NEAR ME AGIAN. THE GUY WHO TOLD ME THAT PLANTED A SEED, AND PLANTED IT WELL BECAUSE IT'S BLOSSOMING, AND I NEED TO UP-ROOT IT. i NEED TO TAKE MY LIFE AND FILL IT WITH SOMETHING. but what? This gay thing is just a brick in the house, ive got so many problems its not even funny, but i need to live through them and perserveere, but nothing motivates. What to do? im 14 and depressed big time, what to do?
