Thank you so much for sharing!
Without chromatic exercise... this could be very hard!
Your hands are not made for guitar!
So if you learn any chord forms... easy one and not easy one!
1) First Practice Chromatic scale everyday for 90 days!
1212 3212 3432 1234 .... 4343 2343 2123 4321
Very important! No metronome!
Only 4th & 3rd string! This way your left hand thumb can be fixed! Place your left hand thumb around center of back of the neck!
2) Learn each R 3 7 form. So not even play blues form.
- Bb7 ( 6 X 6 7 X X = R X b7 M3 X X ) Fingerrings are 2 3 4 and use your 1st finger for muting all the strings.
- Eb7 ( X 6 5 6 X X = X R M3 b7 X ) Fingerings are 2 1 3 and watch my lesson video for how to mute.
3) Don't try any tempo first!
Movement is so important!
Down stroke all the strings and hole a pick super light as if you are about to drop a pick!)
Up Stroke (enter guitar body!) swing really big! Hit all the strings & mute by your keft hand.
...You can not learn songs immediately, because your fingers are not cooperating as you wish.
That's why you must prepare technical part first! This part is very hard to understand because it seems nothing to do with performance.
Hope my comment can help you!
It will take some times but please don't decide too fast!
You can do it!
