Hearts in control

My knees begin to shake
whenever you're in sight.
My mind filled with wonder,
my heart filled with fright.
Why did this happen?
When did this start?
How do I listen to my mind
without breaking my heart?
I'm confused, Don't know what to do.
I can't think of anything except you.
Should I just get over it
or should I give it time?
I don't know what to do
because my heart controls my mind.
