I feel very upset recently I'm applying a national scholarship of postdoctor these days, but the person who is in charge of this in my university does not work seriously that may result in no opportunity for me just like last year. Another thing worried me is the invitation letter. I sent 10 emails for the professors abroad to apply a position and ask for the invitation letter required by scholarship concil, but no replay yet. All the things made me very upset, and I feel so helpless now. What shall I do next?I can't lose this chance again because I will not allow to apply after graduate for 3 years.
