What is the real emotion of love?

There's so many things for me to tell you yet i can't say out or maybe my mind's blank when I'm just with you.
Just wants to be with you alone, hugging tightly, to ensure a secure feeling from you. I know I can't be as open minded as you're. BUT i'm sure that the person you love the most done a most simplest thing, & you'll jealous.

"I'm scared of everything. I'm scared of what I saw. I'm scared of what I did, of who I am."
"It's sad not to be loved, but it's much sadder not being able to love."
"Love knows no boundaries."
