I want to change my ice-cream-store job but I'm fucked for the spring semester

During February I have a lead a retreat for my church job, then the day after I get back, I have to report to the South Beach Food and Wine festival because I got a weeklong "internship" because my school is the one that organizes the event. So that's 10 days straight I meet to request off; then, I already paid my spring break vacation because this year it matches my sisters and we are going to be abroad 5 days. And then! In may I'm doing a study abroad program for 3 weeks!!

There's no way on earth that I can apply to a new job and be like "so I need 10 days in February, 5 in march, and 3 weeks in may. May I work for you?"

I know I sound stupid, but I'm struggling :( I just need support from someone
