Making a big mistake

I have made many mistakes in my life. I'm a very clumsy person. Lately I made a big mistake that has hurt a friend. A mistake I didn't mean to make, and one I feel horrible about. Today this mistake became even bigger and now I worry I have made things beyond fixable. I feel so terrible about it, I feel so terrible that I hurt my friends. I hope they are reading this, because even though I've tried to say it already, I want to say it again, Im very very sorry.
