I'm having a bit of trouble with playing guitar lately. Before coming to college I weighed 104 pounds and I'm m/18/5 foot 6, so I was pretty thin. I've been gaining a lot of weight since then and one of the changes is now my fingers are different, they're thicker, more fleshy, and a bit different shape. I can't play very well anymore because I don't recognize the feel of anything. So, how do I adjust to this?
