I know a guy that is missing his entire left index finger and can play EXTREMELY well. Granted, he can not play just like me but he has adapted to play as his body will allow him to.

Keep playing around with different chords and with enough practice your body will adapt to make it happen.

I am sure if you search you tube or like wise, you will find lots of good tips on adapting you playing style to suite.

Keep going, don't give up and happy playing!!!!
