Should She Freak Out Over an 84?

Sparklers, ACTIVATE! Your fellow Sparkler is in urgent need of soothing words.

I'm in desperate need of someone to tell me the truth, ugly as it may be. I am a junior in high school (it sounds familiar, I'm sure, but please stick with me for a minute here) and I am enrolled in 3 AP classes (english, history, psychology) and three advanced (precalculus, chemistry, and French IV). I try very hard and the majority of my grades reflect that. I have managed to earn A's in all of my classes... except one. Math is positively my worst subject! It's awful! I'm a bit of an english nerd and I enjoy the class which contributes to my success. My dilemma lies in that the math grade on my report card is like a blemish on an otherwise clean face. It bugs and frustrates me so much, I feel like crying and/or giving up on my dreams of getting into a good school.

The thing is, the normal math course for a junior to be taking at my high school is Algebra II. I am, therefore, a year ahead of where the average junior is. As I've already mentioned, I take advanced pre-calculus. The course is very difficult for me, and I try so hard it hurts! Still, on a report teeming with grades in the 90's, there's always that 85. This past marking period I earned an 84 (just shy of  honor roll). IT'S ABSOLUTELY KILLING ME. Call me obsessed or whatever you will,  but I cannot accept that grade. I know I shouldn't be this upset when other people actually failed for the quarter, but I've set my expectations so high that this is equivalent to a failure in my mind. Can you please tell me if colleges will look at my grades and say, "Everything is looking just dandy-- gosh, well.. what do we have here? *GASP* an 84? Not good enough." Is this an accurate reflection of the future because that is what I visualize in my own head. Sorry for rambling on, but I just need to know:
1) Do I still have a chance at getting into a good college?
2) With all the competition out there, will this kill my GPA?
I'm a wreck over here, thanks for taking the time to read this.

What say you?
