The feeling of love

When I see you my knees go weak,
But the butterflies in my stomach keep my up,
When I see you my brain stops,
But my hart takes over,
When I see you everything goes black,
But you create a light for my to see,
When I see you my life seems to stop,
But you are still in all of it,
When I see you nothing can exist,
Because there is nothing more than you.
