Does anyone know what to do if you can't remember what your email or password is?

[cunning quarry]

i made my switch account well over a few years ago and i was at the age where i didn't have my own email or anything, and me and my parents can't remember the email or the password, is there any way to possibly contact Nintendo to get them to change the email/password or am i screwed
