Do NOT turn back positive feedback. Just deal with it. Seriously, it's very, very bad to turn it down.
This is mostly from experience, but the idea of working is that someone pays you for your work and that they trust you to complete the work done. When you show a lack of confidence, it affects how people perceive you and your work.
Generally it's seen as a lack of self-esteem. I won't go that far in your case, but understand that that is the perception and professionals want to be confident in you. But if you can't demonstrate confidence in yourself, then how can they feel they can place their confidence in you.
I'm not saying any of this is the case internally for you. But you're just going to have to accept it. It's normal, it's healthy and overall it's good for your career too. Keep that in mind.
Op commented bellow confirming the point on self esteem. I would suggest maybe seeking some therapy or trying internally to push back against that negative talk. The world is trying to push you down, the world is trying to beat you. Don't contribute to that. You are your own best advocate. You're working hard and you're crushing it. :) You ARE awesome and acknowledge that, because the world won't always give you that credit and you need to be on YOUR side. Because no one else is... well, except for maybe us plebs at Stack :)
