What I need ...

I need to feel that i make part of someone, I need feel that I make someone happy, that my smile makes other person happy .

I need to know that I’m important to someone, that have someone in the world loves me and needs me !
I need to hug someone, and feel that is special, that is a real friend, someone with I can count; I need to feel that that hug had a different meaning, that that person will be always there for me ;
I just need a simple word, that will change all my expressions and feelings !
