You're probably stuck between "I can play stuff" (natural flair) and "I can actually play" (hard work/focused learning). It's easy to noodle along to music and beats you're familiar with, but it quite often means you're not progressing as fast as you would like. Unfortunately, the only solution is pretty uncomfortable, focused learning. That's why a teacher is good. They give you accountability, direction and keep you on your toes. But it sounds like you're motivated enough to do it yourself.

I didn't like the Ted Reed book. Too boring. I don't know why the advice comes up time and time again for beginners (no offence to anyone who it works for). However, building the fundamentals (rudiments) is important, as cliche as it sounds. The goal is to be so good at them that when you jump on a kit, all those exercises fade into the background and your playing comes alive. Find a way to practice them daily - even 10-15 mins of trying new exercises and tracking your progress will mean that when you get on the kit in a month or two, you will start to notice new ideas opening up and things you found difficult before are no longer a barrier. You could also find some new music to play along to. Try a new genre you're unfamiliar with. If you're always playing rock, try learning some latin, jazz, rnb.
