https://www.tofugu.com/japanese/learn-hiragana/ and start looking through it right now, I know how it feels to want to learn a fucking language but always feel like it's too big of a commitment, these concerns will get easier if you do this shit right here and now and see that tangible progress is very much in front of you.
After that, it's a toss-up, the tools people usually use to study Japanese are anki for kanji memorization and the yomichan browser extension as an easy way to scan words you don't know online and also make anki cards. You will need to look into setting these two things up but don't worry about it now. You'll also need to look into grammar guides at some point, do either Cure Dolly or Tae Kim. The most important part of it all is, ignore DJT schizos and do what feels right, but don't fall for reddit-esque toxic positivity either. Try to have fun by translating the type of content that you personally enjoy, mine words from it to put into anki, and read grammar at your own pace.
