Help me to pay my senior year needs

My senior of school is near but as both my dad and step mother are jobless, we can’t pay for the school uniforms and some books, which limit date to pay them is October 1st. We’re neither getting my mom’s alimony till Octuber 15 so there’s no way we can get the enough money on time. I’ve always been and still am the best grade of my class and currently want to graduate being the top one of the class, and losing this year because of not getting my uniform would be devastating to me.

I will really appreciate if you could help me, thanks!
