My man.
Heh, getting template answers from the advisors here?
I'll give you a something for you to ponder, there's no such thing
as easy answer when it comes to the matter of the heart.

You feel something strong, which will compel to do the abnorms or to
react unusually.
You feel nothing, but everything around you looks better and smells
better.
You feel sad; you feel good yet lonely at the same time.
You daydream more often
You feel that; life has purpose
You feel confused because you're unable to control certain
emotions
You feel empty, what comes can go the next moment
You feel love, when you see love coming towards you.
One subject, many ways attainment.
Many interpretations
Many variables
Many ideals
Many dreams.
What others say may not be as true as how you truly
experience.
Think over it. 
Cheers
