Confused

My knees start to shake,
when you're in sight.
My mind's filled with wonder,
my heart with fright.
When will this feeling stop?
When did it start?
How can I listen to my mind,
Without breaking my heart?
I'm so confused.
What should I do?
I can't think of anything,
except of you.
Should I ignore you?
Or just give it time?
I can't think straight,
my heart controls my mind!
