You're not alone! I think every single person who has ever picked up a guitar goes through the same thing. I started playing almost a year ago and remember when my fingertips were so sore I could barely manage 5 minutes! Then the hurdle of getting my fingers on the right strings and the right frets! Transitions from one chord to another seemed impossible. (I won't even get into my struggle with bar chords!) Stick at it! It takes hours and hours and hours of practice to build that muscle memory--and then it happens! One day you will be doing it without even thinking! I still have SO much to learn, but I know without a shadow of a doubt that with time and practice, I can do it. You can, too!
