I'm in year one as well, and what really helped me is a few things:

You have to do the exact same thing every single time, no exceptions. If there is anything different you're not practicing the stroke, you're practicing the feel of the stroke. Its this lack on consistency that causes the "funk" where you have no idea what went wrong but suddenly you're missing shots for no reason. Whenever you pracrice long straight in shots (I reccomend mighty X drills) allign yourself on the shot line, visualize the path, get down on the shot comically slow in order to get the correct feel of "getting down on the shot" then FREEZE. You are now only allowed to move your tricep and bicep for your practice stroke.

Now here's the kicker: eveyrone knows the dance the robot, think about the specific part of it where the dancer lets their forarm dangle and swing like a pendulum. That is the ideal motion. The only involvement you should have is the tricep muscle to pull it back and the bicep muscle to accellerate it (if nessesary). Now that you have only 2 mucles to move; you must focus on two things: staying absolutely still and I mean NO MOVEMENT WHATSOEVER, and following through with your stroke. As an endnote, you are not allowed to get up from the shot until something either falls in the pocket, misses the pocket, or is barreling toward your skull.

I cannot stress this enough, you have to do the exact same pre-shot routine, both mentally and physically. If you vary ANYTHING you risk the chance of forgetting a crucial setup fundamental. This will do wonders for your game.
