(to my audience of 0)

I really want to try writing a yuri!!! On ice high school au, but I’ve never written a fanfic and I’m nervous to try ;o;
In the fic I want to try tackling issues like eating disorders, anxiety, homophobia, family issues, etc. but I don’t know how to go about it D:
Also I’m not sure if I would be able to update often enough to please my audience and I don’t want to make people angry :0

The main story would be about viktor going on an exchange program to a Japanese school, where he decides to join the school’s ice skating club. I can’t really say more without giving away the potential plot sorry.

Also I have no idea where to upload a fanfic, how to go about writing one and pretty much everything else. But I do like writing though and I have to start somewhere :<

Does anyone have any tips to give me, and also do you think that you would like to read a story like this?
