I'm terribly sorry for what I said to you.That was too much for you.I guess you found it hard to understand what I had said.I don't know what I should say now (或:I'm at a loss what to say now.),which is really incredible.I don't know what is in your mind,but I wish you could forgive me.
Really sorry, I said to you before the word is too much, I think you is difficult to understand what I said, I don't know what I can say right now, it's crazy. But don't know how you think, I hope you can forgive me
I am really really sorry, I said something terrible to you before. I think you might not understand what I want to say, I don`t know what I can say now, this is incredible. But I don`t know how you think, I hope that you can forgive me.
