Doubting my badminton abilities

I lost my wrist power...The pain went away but there's a snapping sound whenever I try to rotate my right wrist. I've been playing with bandage to hold it steady but I don't know if it is psychological or not, I cannot generate power out. I used to smash hard but now I fear being in pain and it is causing me to doubt my wrist. In badminton, the wrist is the heart and soul of a player. I've torn my achilles heels but instinct coupled with adrenalin erases the pain whenever I stand inside the court. For some reasons, I cannot forget that I have an injured wrist, and it's causing me to doubt all my shots. I haven't told my partner yet but I'm hoping, really hoping that I can get over this. In life, whenever we hurt ourselves for the first time, the pain lingers to teach us a lesson, and we get scared so that we give ourselves a moment to rethink our actions. Physically, hurting my wrist made me realize how much I have been taking my health for granted. Psychologically, I have been trying to overcome the trauma. And I really do hope that I get over this in time for Sunday's big tournament.
