What's this feeling?

There is this feeling, that I missed so much

I find it to be the greatest feeling of all

I love to sing and I love to dance

I love to act as a different person for one can never know the true me

Only you know the true me

I love to sing in your name.

I love to hold you

I love to talk to you

I love to know you.

There is this feeling, that I don't know of...

What is this feeling?

And why is it happening to me?
