Drew DeVaultAnkiDroid is indispensible. Helps you fill the little moments with studying. Start by learning to read hiragana and katakana, should only take a couple of weeks. Then learn a few hundred kanji, in RTK order, then start studying vocabulary instead of abstract kanji (or keep studying abstract kanji if it interests you, but start vocab too). Use Tae Kim's grammar guide to start getting a grip on the grammar. It may be helpful to use Anki to study vocab specifically for Tae Kim. Once you start feeling like you can hold basic conversations, get a 1:1 tutor on Italki and work on improving your conversational skills. Then seek out IRL native speakers and befriend them (tip: they'll want to practice english with you, too, my friends and I have been known to use an egg timer and switch languages every 5 minutes).
Break down your studies into each constituent part and adjust your approach as you go to cater to what's working for you and what's not. You should have a separate study plan for developing your kanji, vocab, grammar, reading, writing, and conversation skills.
Best of luck!
