It is already done

don't worry about it anymore.  Depending on the culture of your company, you may be in touble, you may not be.  However, either way, it is a good lesson for you.  I got a feeling that things will turn around for you.  Sounds like your 经理 is a moody person.  It is not possible for him to change.  What will happen between you and him depends mostly on how much you boss's boss relie on him.   

Please keep us updated on the development.  Hopefully we will hear good news...
