Hey Robert! There's not much to add after everyone's comments here as they are spot on.
I've totally been where you are before and not that long ago too! The best advice I can give is to really take your time and try (as hard as it may be) to be kind to yourself, at every stage. Guitar isn't a race, it's a journey that you're supposed to be enjoying instead of beating yourself up!
Treat yourself like a student that is paying you good money to keep them positive and motivated. Learn to recognize when you're getting frustrated and pause right there. Take a deep breath, it is really is only music. You'll be surprised how quickly you improve when you stop putting pressure on yourself and just start getting lost in improving the little things.
If something starts annoying you (which it definitely will!) try and steer your focus to what you can already do (that 1000's of others can't do, that have never even touched a guitar, or have it sitting collecting dust) - You're actually hitting the grind and trying to improve your craft, and your frustration only shows your passion for the instrument - which is a really positive thing! Your passion and drive will sail you through the whole process in one way or another.
Remember: Playing anything on a guitar is by no means a natural ability of the human body, so it says absolutely nothing about your worth as a person if you struggle with something! Every guitar player you'll ever look up to or feel jealous of feels frustrated about something in their playing.
For me, mindset is everything when playing your instrument. Your mindset determines your attitude to what you're doing, and your attitude 100% effects how quickly and effectively you will learn and progress on your instrument - nothing else.
So In a nutshell: Be kind to yourself, Don't Compare Yourself to others, Be proud of how far you've come & Enjoy the learning process!
