For me it's a little... okay I should probably get into it.
My parents and teachers have been supportive of me writing since I was a child, but then there was my teenage years where I was writing edgy stuff... and then there was a time where I stopped writing in general. But then I felt aimless and went back into writing and then I met this person who helped me. I won't go into the specifics of our relationship we were both at the lowest points of our lives, but the dude flat out broke me... to the point where I think he did something to me mentally? Especially since my brain was just vulnerable from my PANDAS disease.
Like usually I'm complacent but all of a sudden, I managed to push and learn to write just to get some validation from him. I never talked to him again because he's a black hole, but in a way I think he shaped the way I am as a writer? I'm hyper-focused on details. I can't stand continuity errors. I don't just write for myself, I try to please people in a ME way.
He also got me into wacky sci-fi with "Hitchhiker's Guide to the Galaxy" (dude was a super nihilist), although I started getting into religion again and that shaped how I do things while helping me with my confidence. My Dad also started reading my stories and he would always praise all my stuff again (although I feel like he wants me to write for me most of the time).
But I wanna say that Kurolines (an Australian artist) was the person to just... SOLIDIFY my confidence. Dude's been my best friend since we were both like teenagers online and I respect the Hell out of him. He's been reading all my scripts and he's been telling me what to do while giving me proper support without being mean.
That Stick Figure Isekai was like the FIRST script where I didn't need him to read my scripts anymore and that happened to be my first fully released project. Felt like the training wheels were off. We still talk to one another and he's checking out my other work. It's so cool to have a friend like that and I thank God.
As for my Mother tho, I think she was more realistic and only supported me ONCE I found success lol. I don't blame her tho, I've been this for years and she balanced out my Dad's optimism.
