You keep ignoring what people are saying and just repeating yourself. Everyone has given you excellent advice and the poster above told you literally exactly what to say.
You can’t leverage jack, because you have pretty much no skills yet, even if you think your college is competitive. There are surely hundreds of kids they’ll take instead of you if they don’t want you anymore, but you literally CANNOT AFFORD to take the internship without pay, so either you suck it up and ask or have to resign regardless. Do exactly what posters have suggested, and if it doesn’t work out oh well.
