Same problem that's why my reading list is like that lol. Just that it really comes in handy when you're bored BORED. You suddenly have something to read. Just scroll down on your list and you'll get into something eventually. But if you then suddenly get bored with the story, just quit the site and do smthing else lol. Then come back and ask for more reccos here. Just...my advice is..."you'll live. you can't win in everything
A good thing would be using the notes app (or any other) to document your opinion or make a little resume father each chapter or ark, so when you drop a one and want to read it again you can check your notes to refresh your memory.
its like writing by the corners of a textbook so or leaving little notes on the books you read

Having ADHD is a blessing, but more of a curse. Sure I can easily forget abt manwhas/mangas cuz I like marinating. But the problem lies when I have so much to read that all the stories I’ve been reading just gets buried in my reading list and the ‘out of sight out of mind’ starts kicking in, making me forget all the stories I used to read. Another thing is that if I wait too long, I completely lose interest in what I used to get so hyped abt T-T AND THEN ANOTHER thing is when a story has too many chapters (esp in manhuas), I get tired of it and take a break from it, then completely forget that story even existed???(╯°Д °)╯╧╧ Then I’d get too lazy to read everything again if I ever come across the story again. I just can’t w myself man…
