What if I'm scared to confess to the love of my life?
That's awful. What scares you about telling her?
I'm afraid that she would reject me and our friendship could end.
Letting someone know your feelings about them can be one of the scariest moments of your life.  But it is also the most rewarding!  I say you should let them know how you feel if they're special to you.
You are right. I'll tell  her before I lose my chance.
I am glad that you are taking a chance by telling her how you feel. It would be better than to suffer in silence.
