My Proposed PhD supervisor is ignoring my email I made a contact with a proposed PhD supervisor( Professor), everything went well and she forwarded the email between her and the department Research committee secretary that I have been shortlisted for studentship and recommended for Fellowship, in the email she sent to me, I observed a remark on my application file (my entrance requirement was indicated with FAILED) and I quickly asked her if it won't affect my admission, but she ignored it, a later found out that all applicant were initially categorized as a masters holder (I am a bsc holder) before screening that was the reason why for that). After, a couple of days, i asked her if I was later shortlisted for Fellowship but she ignored the message, though the admission offer will be released in March. 

My questions are these;
Hope I have not create a doubt in her mind towards me as a result of my inquisitive nature?, hope this won't affect my admission offer and lastly, how can I build the relationship back because she used to reply my messaged often and appreciate my research proposal?
This is obviously an important decision for you, and it's understandably making you anxious. However, you have to accept that the decision won't be made until March. Repeatedly contacting the folks making the decision, asking if they've decided won't help. They have a process they have to follow, and they can't make promises before they've completed that process. Sending repeated emails asking about the status of their decision could be annoying them (it would annoy me), but if they're reasonable, professional people it probably won't affect their decision on the position. However, no one can guarantee that. You just have to live with the uncertainty for a couple of months.

As long as your application is complete and accurate you should just put this aside until March. Find something else to keep yourself busy, or seek professional assistance if the anxiety is overwhelming.
