Crush, hush

Is there ever that one person you just wish they knew you're more than head over heels for? How hard can it be to say a bit of simple words like, "i like you". Knees get shaky, heart is pounding and all the time you're repeating to yourself "don't be a coward, just do it". I don't know how many times it can be repeated before it's understood. Would it be better to keep my crush a hushed secret? I'll soon find out.
