Lots of good replies here and I have little more to add… the main thing to remember above all is consistency. Try to play every day for at least 10 minutes but that doesn’t have to be a speed limit… you can go longer but only if you are feeling it.
It has been a long time since I first started playing and for some reason I got a 12 string guitar to start which was not a good idea. But I remember the same frustration. Definitely dial back the speed or even just play the chords on your own. That coordination only comes with time and repetition as your muscle memory kicks in as you transition from every chord to every chord.
I really like the advice here about moving on and not requiring mastery of yourself before you continue. My practice routine pre-AC was to work on a technique/song/new chord kind of randomly but I’d keep adding things and never mastering the earlier things… though I’d keep them in my routine until I felt I’d mastered them. The result? A VERY long routine with a whole bunch of things I couldn’t do. Moving away from something before mastery I know is difficult… it really bothered me a first but now I find, working on other seemingly unrelated techniques impact everything and when I return to things I did not master, I’m a lot better at them even without having practiced them for weeks! It isn’t magic, it’s just that fundamental techniques develop over time with the method that can be applied to lots of different styles, exercises and songs. It really works! Be patient with yourself and understanding of what seems like slow progress. It will come with time and perseverance.
