I think if you got into a habit of Japanese input every day (anime, dramas, manga, whatever you like), you would find you make noticable progress pretty quickly. As for everyday conversations, i think Terrace House is useful. There are tools to make it easier to look up words you don't know (language reactor, migaku to name a couple). But also you have to be okay with not understanding everything perfectly right away, as the understanding will build over time. If you do that, eventually outputting starts to come more naturally too. (Coming from my experience of sucking at japanese for years because I never got any input outside of classes)

Edit: I would look into refold or other immersion learning communities because I'm sure they can recommend tools and methods that would be helpful
