spoke too soon

Of course, I jinxed myself. I was working on my shawl and found myself short a stitch. I added a stitch in, but now, the pattern is thrown off. All my yarn overs are shifted 1 stitch to the left, meaning I no longer have pretty columns. And of course, I didn't put any waste yarn in. I know if I try to unravel I'll just wind up with a mess of clumped yarn. GRRRR. Words of wisdom welcome . . . I'm going to look for a bridge to jump off . . .
