Give it time and eventually one day you’ll realize everything is coming really easy. Also, I used 9s on my guitar when I first started 8 years ago. Its easier on the fingers. Although now they’re way to light for me so I use 10s on my tele and strat. Just practicing chords gets boring as hell so find an easy ass song that uses a couple different chord changes and work on that. For me the D and G open chords were tough cause of my fat fingers when I started so I learned them on Sublimes what I got. Those are the only two chords in the song.
