Take a deeepppp breath. First and foremost...you are going to a convention FILLED with women who love romance and are unapologetic book nerds. Seriously, that has to be one of the least scary groups to be around. Oh, and these romance loving booknerds are also there to let their hair loose, party, and meet new people. The booze will be flowing, the laughter will be plentiful, and at the end you are going to feel SO GOOD about yourself that you had the courage to go and I can 100% guarantee you that there will be someone even more shy than you there.
So, put on your big girl panties, strap on your beer helmet, and have fun!
