I'm ready to leave work now

I'm a full time student and have two part time assistantships at school. One of which I just spent weeks trying to organize a meeting with over 30 people for a presenter and now two days before the presenter tells me she'd rather do it next month because she didn't have enough time to invite the people she wanted. 😑 ... Now I'm going to have to cancel the meeting and it'll look like I can't do my job. ... So ya ready for maternity leave now. Anyone else?
