Mid-Year Grades TANKED!! Help!

I have requested for my mid year (first and second quarter) grades to be sent to all the colleges that required then. My first quarter was okay-not the mid to high 90s like in junior year though. However, in AP Bio I basically got a C. Now my second quarter grades have just been released and I am having a nervous breakdown because I got an F. I am taking 5 APs ( AP: Bio, Calc AB, Econ, Lit, and Italian). Everything else is okay except an F in Bio and a C in Econ. The others are all low 90s or high 80s.

GUYS I am really really freaking out. I understand I should not have let it get this bad and my laziness is the main reason. However, I am planning on sitting down with my GC and explain my situation. I have had a tremendously hard time in my personal life with some parental issues. After I open up to my GC I was hoping he could somehow contact the colleges and explain how this situation has had a great impact on my grades. This is not some bs stunt-- my circumstances at home have had a large impact on my school work. Is this an acceptable plan of action that can help me?

I am applying to some top schools for business including Stern, Mich (if I am lucky to get into Mich then it’ll probs not be with a Ross acceptance for the second year but that’s okay), and even Cornell. PLEASE tell me what I should do!!! I have (thankfully) two acceptances to lower-tier state schools but I still want to see my chances at higher schools. Everything else is solid except my Mid-Year grades. How much influence does this have??? Please I need anyones thoughts on this crappy situation!
