This is also I thing I struggled with for a long time and there was one thing that kept telling myself until I actually believed it “Nobody will remember or even cares and if they do judge you screw emm there not gonna be your friend anyways so why give them space in your head” I had this exact problem in the gym, I was so scared to start benching becuase the weight is so obvious and I see these dudes benching 2,3 plates for reps and I could only do one,then I kept telling myself this and I eventually got rid of that fear
