你竟堕落到如此地步，太令我失望了。

I'm disappointed that you've stooped to this!

我希望这次的手术你会在我身边支持我，好让我觉得你对我曾经负责过，可惜你少少责任永远都做不到！你令我太失望了！

I hope you can stay with me during the operation and stand by, so it seems you were ever responsible for me, but you are so regrettable & lack of responsibility and really let me down.
