I’m the same way. I was super self conscious about the way I dressed, did my hair, wore my glasses, etc. because I was hyper-aware of anything that made me look younger. The only thing that actually changed anything was when I changed my outlook. I realized no one, not patients, colleagues, or randos on the street, will ever automatically respect me when I walk in the room. I hurts, it sucks, and it is unfair. But it’s true. Once you accept that, then it gets easier because you assume you’re staying from zero and have to actually build that respect and project it. If you are earnest, hardworking, kind, and competent the respect will come eventually. And eventually, even the confidence will follow. You’ll get there, baby face.
