Is this an ongoing problem or just this knitting session? Either way, if you work on something else for a while that you can relax more with and come back to this after a break, that might help. I can see where the "gotta get this right" thing could cause me problems I shouldn't have.
Cheating is an option. . . . Cheaters never win and winners never cheat, but smart knitters who want to retain an iota of sanity do, cheerfully. ~~Kory Stamper
