Love...

I don't know what love is...
I thought it was when you squeeze someone on your chest and make him feel like it's all yours.  But i just got fooled by it...
Love is not that- cuz you get rejected.
So,  i don't know what love is...
How do you love? What do you need? Some utensils? What kind? How?
I keep asking this... What love really is?
When you tell someone what you feel? When you show it? When you make it memorable?
How can you tell you love someone? When your chest is almost killing you,  not letting you breathe? Or when your heart is getting out of your chest just because you saw that person?
How does love feel like? Like living? Like dying? Like wanting to go on? Or giving up?
Or maybe you need a special book? Or a recipe with some special ingredients that not even the most powerful witch knows where to find them?
I don't know what love is...
But can someone teach me? Or everyone is stuck at this question, just like me... Wondering all their lives "how do you love"?
