I'm sorry too! I've had it happen too, when you are following gauge and the project turns out too big! Had that happen with a sweater for my dog (not a Bernat pattern)--and once on a pair of mittens. They both are a little big, but still wearable.
I had a totally frustrating time last week trying to knit a VERY simple scarf (cast on 22 st, work in stockinette stitch) using eyelash yarn. I dropped stitches, added stitches--ARRGGH! I am I guess what you would call an "early-intermediate" knitter and this made me feel pretty inept. Frogging was impossible, due to the nature of the yarn.
Finally I gave up and abandoned the good ship Eyelash Scarf.
I just moved on and focused on my strengths
and counseled myself by admitting I really don't need a hairy, furry scarf; and also really did not care for the color choice I had made anyhoo. We all get bad knitting days every so often. I guess they are just teachable moments.
