Same here.. applied to 6 program got 2 rejections (which were expected) but have not heard anything from the other 4 schools.
The same happened when I applied for PhD 2 years ago.. did not hear anything till end of April then started getting rejections from all 10 programs I applied.
I am starting to lose confidence and can't focus on my work these days. My friend keeps saying me to stay positive because he got acceptance in June for his PhD... But it's getting real hard to have some hope!
