Possible C in 12AP English...is my UC future over?

Okay, here comes the stats.
Weighted: 3.97 Unweighted: 3.6
SAT (new!): 1100 (yes I know it’s low…my counselor advised me not to take it a third time because I wouldn’t have time to do some hardcore studying.)
I took three APs my junior year and I’m taking three right now, but keep in mind that my small school has a very limited pool of APs. We only have English, Spanish, psychology, Euro, APUSH, calc, physics, and art.

My AP lit class is a nightmare. I hate to be the brat that says: “The teacher hates me! It’s unfair!” but that’s honestly how I’m feeling. I keep up with the reading and technically doing everything right but according to my teacher my writing is downright atrocious. Last year in AP lang I was doing a decent job; I was getting 5s, 6s, and 7s and got a 3 on the test. Not amazing, but not horrible. This year I’ve gotten one B, two Cs, and one D on my essays and I am devastated. I’ve talked to him and he said: “You have one run on. You said the narrator was a child but didn’t tell me exactly how old she is.” and many other tiny details. I see my friends make one less mistake and way away with A-s and B+s and it crushes me, but I’m not a confrontational person so I can’t attack him on every bad paper. If it keeps going on like this I am going to end up with a C in the class or be forced to drop down to prep English…is it all over?

My top school is UCSB but I’m also applying to UCI and UCSD (technically my dream school…but who are we kidding with that SAT.), should I even bother to finish my application? I thought that they could look past my SAT score and focus on my passion for my grades, art, and my senior project but now I’m not so sure. I have two cal states that I can get into so technically it’s not all over, but I would hate lose the boost for my career that I would get from a UC.

I am planning on seeing my counselor next week and I’ll bring this up, but this whole thing has me so depressed…
