Autistic 23M, any tips on how to make my autism less obvious?

I’m aware of the concept of masking. I’ve been doing it for years. I’ve been getting better at it, but i’m still not quite there. And before anyone tells me that i should be myself and i shouldn’t mask. I work in a hospital so i don’t have that option, and even if i didn’t, i would still want to mask since i don’t feel comfortable with people knowing im autistic. But i still feel like im missing something because i feel like a robot mimicking social interaction. I don’t want to be seen as autistic because i’ve been heavily bullied for being autistic in the past.
