ig i need attached to someone for living

I realized this recently and it is my weak point. I want to dedicate my life to someone. To be far from being alone and always need someone. I have many friends but I feel lonely. I need a boyfriend but depending on someone seems so lame. I am stupid enough to give my whole life to someone I love. I am like a dog in a relationship, I loved and cared for them. I'm so naive and it makes me have an inferiority complex. Life is so complicated and difficult. Damn, im so good for this world. 
that one quote i saw on facebook years ago says:

the world is a hell for ppl who has good heart...
