Don’t worry about other people thinking you are deluded. Don’t give other people that kind of power over you. You cannot control what other people think so tune them out. I have had to do this so frequently for so many things and it feels hard at first but it gets easier.
My son decided he wanted to act at 8, because I am a big proponent of letting children explore their own interest, I was supportive. It turns out he was/is really good. Consequently, over time he started working professionally (he’s not a name, but he has some credits which is good considering we live in TX and not NYC or LA). Of course, tons of people assumed I was driving it and I was some kind of ‘stage mother’ and was pushing him and living through him. Nothing could be further from the truth. He’s highly gifted in math, so my dream for him was to be the next Bill Gates. Ha! Not happening, he prefers the arts. At any rate, it used to really bother me the assumptions other people made about it. What I learned over the years is people are going to think what they think about me and there is very little I can do about. It is neither my responsibility nor within my capacity to change their minds. It’s perfectly okay to say “Thanks for your concern, but I am okay.” That’s having healthy boundaries with others and it really will give you peace of mind.
