Its hard to explain to ppl off the bat for sure lol
Most of the time I claim I draw ppls characters n even then others are shocked u can make money off of it which is odd.

Same here!!! Its always a strange conversation to have

I'll be honest: I think the reason you're feeling this way is you're still so young. You've spent the majority of your life living under the instruction of people that demand your unconditional approval, teachers, parents, etc. Part of your life has involved trying to get their support because their decisions and support can drastically effect what happens in your life.

When you get older and more independent, you realise that these people really only had any power over your life through accidents of circumstances. They're not necessarily better or worse at knowing what's best for you, especially if they literally don't have experience in life. Don't be too harsh on them though, they looked over you when you were in your most vunerable state, and probably taught you a huge amount of how the world works to the point you consider what they taught you "obvious" and what "everybody knows." At some stage, they genuinely did have a lot of important things to teach you and guide you on, which at this point you've either taken to heart or consciously rejected.

But now you're going your own path, and while it's the right one for you, it takes you out of the shade of support from those you looked up to your whole life. Of course its unnerving, to some extent you are stepping away from all the support structures you knew of, going off the track everyone who guided you assumed you would take, and finding yourself in unfamiliar territory. You're getting a lot of new support sure, but your mind still thinks of the old support that you now fear you are leaving behind.

This is something that WILL get better with time. You've nailed the essential bit: Financially supporting yourself with a decent standard of living and with an occupation you enjoy. I cannot overstate how amazing this is. There are people who struggle for years, even decades, trying to achieve what you have now so really appreciate how awesomely you're doing right now.

With this base laid down, you'll gradually become more comfortable with the life you've set out for yourself, and realise being open about who you are and what you do... well, sure a few people will turn their noses, but you'll also get a lot who are curious and interested learning about another walk of life they didn't know about, and others may even end up commissioning you themselves!

Ultimately, when you're living independently, there's no real authority you need approval from. Teacher influence fades as you move on from their courses, and you see parents more and more as regular human beings with time (with strengths and weaknesses like all humans). You become the decision maker of your own life, you realise that nobody else has that role. And, to an extent, you get to say how the world should be, how things are and what works best for your life.

As I've said, I think you've done pretty damn well so far. I genuinely wish you the best, and take care!
