I agree with everything that has been said above. It sounds like you have a "Mike". When I was 17 and bought my 1st guitar, my best friend at the time (Mike) had a much easier time of learning the instrument than I did. And man it did not sit well. My guitar and he can play it better than me. So, I let frustration get to me... 38 years later I learned to play it!

As it has been said (Moe I think), try not to compare yourself to others. And if it is nerves, embrace it and jump back in. Sounds easy I know, but its honest.
