Do you recognize this?
It is then very likely you suffer from imposter syndrome. Many PhD students struggle with this.
This TED film explains it all and gives you tips on how to combat it.
This feeling is extremely common
Knowing this will help you seeing your imposter thoughts in perspective and taking them less seriously. In the book Playing Big that I mentioned before, you will also find many practical tips.
And, just to be sure: I know you are not an imposter: otherwise, you wouldn’t have managed to become a PhD student!
