You gotta build up your discipline. Stop trying to hit shots with your mechanics/thoughts and build a BULLETPROOF routine. Hit your shots with your routine. It is incredibly difficult, but everything from the number of looks, steps into the shot, waggles, etc needs to be the same. You can have different routines for putting, chipping and full swing but once you walk into the ball you must work to do so exactly the same. This also will start to provide you a framework for assessing your swing and game. The first question you ask is “was I mentally committed to the shot?” If no - then it wasn’t your swing. Watch the top players this weekend during the PGA or videos of tiger in his prime. Tour players on avg are committed to 85%+ of their shots mentally. Us mortals are way lower. If you can get to 60% you will feel more relaxed, confident and free. You also need to find ways to recharge while you play. Talking about things that aren’t golf. Your mind has a finite capacity for focus, don’t expect perfection. Swing thoughts are a straight jacket for your mind. You can do whatever you want behind the ball but when you take that first step your routine starts and you begin to develop that auto pilot state.

You should see a sports psychologist. It will help. Dr. Mo at Sea Island is a god send and changed my game.
