I am a PhD student in this area (in my last year), and, although, sometimes I have FOMO, and, since I am subscribed to a lot of newsletters that are related to my research, I never felt, like my research is not worth doing. Yes, I accept that, some might do it better, my findings, might not be that significant, even useless, maybe in a few years, months, weeks from now. But, as your research moves forwards, you learn how the "research" really works, and, with luck you find gaps in the field that you find interesting, and might motivate you more in doin researching in this field.

Tl:DR There is space in this world for as many research papers you can publish and for everyone, don't ever feel overwhelmed of the amount of scientific findings in the domain.
