People who worry about what other people think when it's noone else's business are rarely doing what they want in life or getting what they want out of life. Know how to get better at something? Keep doing it.
I had a while where I couldn't get much on deads... my weight was less than with squats, and it felt weird doing them. Figured out my ass was too low and I was effectively squatting the weight instead of deadlifting it.
Keep doing them as you can, you'll get better. Maybe vary it a bit so you do some at high weight really low rep and or the other way around and see if that helps. Make sure your ass is high enough, make sure you're activating the right muscles, and just work on them to make them better.
Or pussy out, give up, move to something else and never get better at them, but at least you won't have to worry about what people who don't give a shit about you think.
