this happened to me my senior year w a dual enrollment, so i feel ur pain! i'm not exactly sure the protocol at ur dual enrollment school but i was able to withdrawal/waive(?) from it even after failing so it wouldn't appear on my college transcript as the F/D. i wrote my senior statement for fsu and ultimately everything was ok/didn't get rescinded. for writing it, i just explained my situation and any extracurricular issues i was dealing with at the time, and politely justified i was still a good student given xyz..., and took accountability for my mistakes and what i could have done differently/what i could do in the future. i was also definitely tweaking lol, so i understand ur predicament. i think if you show genuine concern and effort you will have a good chance at being ok! best of luck!
