Currently, I am applying to funded PhD programmes in Europe. Not long ago, I thought it would not be so competitive, but now I am losing my self-confidence, receiving constant rejections. The other cause of my frustration is that I want to get an offer faster since my home country is invading Ukraine, and that is why I might be (at least to some extent) judged by my nationality or banned from getting visa. I am trying to make more applications, but their quality decreases, and I am becoming depressed. Some university has also rejected me, claiming it could not approve my forein degrees, which is also very insulting.
Here is my short background. I have a bachelor degree with 98% GPA from noname university of a second-world country, master's degree from a world top 50 university with 95% GPA, two Q1 first-authored papers that were cited more than ten times during the first year. I also have more than five years of industry experience.
So my question is how to overcome frustration and imposter syndrome during PhD application process? How to deal with the fact that I could be rejected because of my nationality and bureaucratic requirements to education?
