You gotta pick your head up, feeling sad/down isn't going to help you get off the waitlist! You worked hard for 4 years to get through school, and you have to remember that it's a huge accomplishment to get a degree. Not everyone has the chance to get a degree. At least enjoy your graduation, by recognizing all of the sacrifices you made and all of the people that have helped you along the way. They sure are proud of you, regardless of this cycles outcome. All you can do about waitlists now is wait and hope something works out. If it doesn't, fuel your frustration to kill it next cycle.
