hey honey. yay for starting to write! i can very easily and very confidently tell you that you're not the only one! there's no correct way or speed to write. i don't think this is how it should be evaluated at all. i think there are many factors that makes writing slow or fast, and it includes what type of story you're writing, and how clear it is in your head before you open the doc to write, and also most importantly in your case: how much practice you got!
if you're only just starting out, it's perfectly normal for it to take a while! i feel like the most important thing to do is not let it frustrate you! because the frustration will only make it even harder to write, and will leave you unsatisfied with what you produce. it's perfectly okay to take your time with it. i've been writing for a while now, and while some of my fics were written in a couple of days, some of them took me a whole year! so there's no right or wrong here. try to remind yourself of that. it's very cheesy but enjoying the process is really why we do this. there's no deadline with fics (i guess except for fests lol) so you can take your time with your story to tell it properly!
have a good time writing honey<3
