Good luck making it through the rest of the year. Hugs.. Sounds like you are getting a lot of good advice. I've been there and I think you just have to take it one day at a time.
I know what you mean about doing badly in one class affecting the others. This happened to DS freshman year. He was really only having problems with 2 of his classes, but his anxiety & depression of the whole thing bled into the rest of his classes. And then lowered the grades in subjects he finds easy like math because he suddenly wasn't doing the homework for them either.
As to IF these grades affect college probably not. My DS's high school, junior high grades are not on the transcript even if they hare H.S. classes. (Only affects foreign language & math classes) I only know of one university that look at grades in any class taken before 9th grade, and they only look at H.S. math taken in 7th & 8th. (And it's self reported) And most of my state universities only look at grades 10th grade and older.
