Is it too late?

There is one person in my life I need to hear from right now. I've left so many tentative voicemail messages to no avail.
If I've fucked up utterly, I need to know. Talk to me.

Please know how important you are to me; I need you, I miss you. I'm cold, hollow without you.

I'm ready to get down on my knees, to repent, to get into great detail about why exactly it is I've disappointed you so badly. To apologize.

Please?
