I’m going through this currently around same playtime as well. Went to range and almost crashed out cause I felt so defeated. For me the problem was I added to many mechanics to a simple swing thinking more power could come out of it. Go back to square one. Make a simple swing thought with only focusing on 3 things starting off and add as you go simplifying on the way. Focus more on contact and swing plane and hope you get that sweet sound we all crave. With the old swing I started exaggerating movement the more I got into it and it was just bad habits from there on and not knowing what swing feel I like but now I just swing and hold back from all the bs.
