I also struggled with French in high school. I found it very helpful to use it outside of class. I started spending an hour a week with a bilingual friend just speaking French, and watching TV shows and movies in French. This can help a great deal. You might want to see if other people from your class would want to have a “déjeuner français” once per week where you get together for lunch and just speak French (however badly) for the entire lunch. If you have Netflix, the last time that I looked (which was a while ago) there are a few good shows/movies in French. Again a while ago the BBC had some good French introductory classes on line.
However, even if you do this it is likely to be better to do well in regular CP French than to do badly in honors French.
I agree with @happy1 that it is very hard for us to know how strongly you are struggling with this particular class.
