Really good excuse for failing a cl?

ok...so the deal is..i just finished my freshman year of college and I FAILED Calculus 2. the problem is...I'm trying to go to medical school. first semester...I took 17 hours....a 5 hour bio course (got an A), 4 hour chem 1 course (B), 4 hour calc 1 course (B), 3 hour public speaking (A) and 1 hour bio course (A). so my first semester GPA was a 3.52. second semester...5 hour bio (B), 4 hour chem 2 (B), 3 hour brit lit (A), 1 hour bio (A), and......4 hour calc 2 (F). GPA for second semester...2.52. Therefore...overall freshman GPA...3.029. Given....I didn't try NEARLY as hard as I could have....I know I could have gotten a 4.0 both semesters if I put forth 100% effort as I should have. But...Med school is my DREAM and i CANT give up on it. future info....next semester i am retaking calc 2 (4hours) plus the 15 hours of courses (including orgo, plant bio, clinical applications of med ical practice, and biochem). I have calculated what my GPA would be if I got a 4.0 and by the end of sopre year i could potentially get it back up to 3.55....and by junior year (if i continue to get 4.0) a 3.7. However.....this is ONLY IF i can get a 4.0 for the rest of college...which I will admit will be EXTREMELY difficult. But...my question for you guys is...given I get my GPA up to where it needs to be and do well on the MCAT, what is a REALLYYYYYYY GOOD excuse for failing calculus? because I know that I will get asked about that in every interview. so please give me any advice....this is seriously my dream and i will do ANYTHING to see it through. BTW, my calc grade suffered because i absolutely HATE CALCULUS....like despise it...and completely ignored it and put all of my effort into my science courses that are actually interesting to me...but I really want to give the admissions people a GOOD REASON....much better than that. but...I also want to be real with them..like i dont wanna go in there and lie...sorry to ramble...but i will take any advice/info concerning this...thanks guys!!!
