Am I too young?

I’m 18 and I graduated high school early and immediately went to school for esthetics. During school I was always the youngest there and only a few people were close to my age.

I’m now newly licensed and I’m applying for jobs. I’ve applied at lots of wax centers because I have no prior experience. I have an interview tomorrow at a wax center and I just don’t want to make anyone uncomfortable (clients and coworkers) at any job because of my age. I’m probably overthinking but I just feel lower than everyone else because of my age. I was always treated like the baby in school, and I don’t want to always feel like that.

Has anyone else felt like this?
