If you want to get good at the guitar and you're having trouble doing it on your own, what worked for me was going to a local commuter school. It's in person, which works better for my learning style. And the level of instruction was better than most of what I'd found was available to me online. I think getting into a serious music scene where you play with other people daily or close to it, whether that's through school or something else, is a great way to go.
If you're practicing the same things and you've plateaued, it may mean it's time to figure out different stuff to practice. What are you bad at? What's your worst skill? You haven't learned how to read (the Berklee Vol. 1 book is a good resource for learning to read with no experience), so there's that. How's your comping? Can you play chords by ear to accompany people while they play? Maybe you can learn how to play chord melodies and self-accompanied solo guitar stuff. Or you can work on your fingerpicking in the classical tradition. Or your acoustic flatpicking.
It's like a game of whack-a-mole. Whatever you're shitty at, you start paying attention to more for awhile. Then once you're better at that you find something else where you're lacking.
Ted Greene's books and Mick Goodrick's books on guitar playing offer the best technique training you can find short of a teacher who has learned from the masters.
But more than anything, find people to play music with. Any setting is good.
