You write amazing stories and your fanfiction doesn’t suck!
Stop beating yourself up because you’re not meeting some kind of invisible quota of likes or kudos or reviews or reblogs and be proud of your incredible work! You worked hard to create that story! You researched and slaved for hours, days, weeks, months, maybe even years to create your piece of fiction. And not just anyone or everyone can do that – oh no! Believe me; writing is a skill and it takes dedication to actually sit down and churn out those chapters.
So be happy and proud and know that your work is making people happy!
