>>26946425The biggest recommendations I can give are either taking a college course or finding a private tutor, but I understand that might not be viable for everyone.
The big thing about doing one of those is they give you a foundation. It's a lot easier to learn the basics of grammar and whatnot and have it become ingrained if you're learning it from someone, rather than trying to teach yourself, but it's still doable even if you can't do that.
So, what you'll want to do is as follows:
1. Spend a week memorizing hiragana readings.
2. Spend a week memorizing katakana readings.
For both of these things you can just use something like this

3. Download anki. I recommend the Core 6k vocabulary deck or Core 10k, but there are other decks (like a Tae Kim deck) that include grammar too. Pick what you think is best for you.
4. Look up Tae Kim's grammar guide and start following it while studying vocab.
4.5 (Optional) After you have a bit of a foundation, you can start learning kanji radicals to help you. I still don't know them, I just learn vocab/invidivual Kanji.
Anyway, once you're learning grammar and vocabulary you can just work your way through it. Start getting a grammar workbook maybe.
Make sure you immerse yourself the entire time too. Keep watching anime, VTubers, and when you're confident enough start reading manga and shit in Japanese.
Make sure to use an online application like Jisho. It's a dictionary that lets you look up words in english, romaji, or Japanese that you don't know and get a definition in EN or JP. This is integral for daily learning.
Use animelon, it lets you watch anime with JP subs and look up definitions/add words to anki, while also having EN subs as an option.
Basically, keep doing what you're doing but slowly "ween off" the EN subs and move to JP subs and tons of JP reading and listening.
After a year or two, you'll start to really get the hang. Progress may feel slow, but don't give up. Find something you're passionate enough about (Like a JRPG series that doesn't get localized, a chuuba that doesn't get subbed clips, etc.) and constantly use it as a motivator.
You CAN learn Japanese.
