Hi MadWatch,
I’m sorry you’re struggling with these feelings around your study. I’ve got a few thoughts:
First, you’re definitely not a piece of shit and your studying is not all for nothing. Honestly, doing those things every day for two years is amazing, and I think you should see that as a towering achievement.
Second, I’m wondering if you have expectations on yourself that are just very high? I expect waaaay too much from myself and really have to keep an eye on it, because it usually makes me not see the good things.
I do think that WaniKani’s marketing about learning kanji in a year means some people think it’s the norm, but it’s definitely not the common experience, and a lot of people talk about it in the forums, so you’re in the right place! Personally, I tried going hard and learning as quickly as possible, but I burnt out, and I also wasn’t learning properly, and that’s because that’s just not how I learn. I’m now taking it much slower and my recall and learning is a lot better.
I also think it’s worth remembering that even if you’re learning via an institution, it still takes YEARS, and that’s with external things like teachers and tests etc. Manga is probably too advanced for now, which isn’t a reflection of you! If you found a Japanese university textbook (you can get them secondhand pretty cheap) you’d likely find you can read a lot more than you thought.
I do think you’re right in your ask already about thinking different learning methods will help - it’s way more likely that what you’re doing now isn’t working for you, as opposed to you not being good at those methods. I find only doing online learning doesn’t work for me, so if you can find/afford a tutor, Japanese textbook, or a learning group you could join, you might find it helps, or you could get a university textbook and teach yourself. Duolingo is also notoriously tricky for learning languages - I found I was good AT the app, but took nothing with me into the real world.
Also - remember that you’re already speaking more than one language, you can definitely learn another!
My final thought is if you’ve always struggled with retaining words, it could be worth looking into dyslexia or even ADHD, but that’s a very private matter and up to you. I will say that getting an ADHD diagnosis a few years ago has contextualised so much in my life and helped me be so much kinder to myself.
Even if nothing I’ve said resonates with you, I think it’s great you’ve reached out here - it takes a lot to ask for help sometimes, and I think shows how important this is to you.
