Eek - FC frogged

Decided to carry on with my FC shawl during a study break - what a mistake. Was obviously not concentrating. Initially ended up with an extra stitch, so I removed a YO, because I couldn't tell where the extra stitch came from and carried on. BIG MISTAKE!!! Just went downhill from there. Ended up having to frog my entire shawl. Feel a bit too devastated at present to start again from scratch at present :(
