My prof was just busy at the end of the term. She finally agrees to be my reference after I sent email two weeks ago. I was struggling all the time and so regret.
This is the second time I ask her to give me a reference. It just too hard for me to survive in this world. Without people's help I just couldn't make any progress. Anyway, I will never ever ask reference from her. She may tired with me. I don't know who can provide me eference for my PhD application.
Another good news is that I can print at lab now so save my money. Yeah! back to work now.
