Should I continue with French?

I started taking French this year, and got up to French II (my high school is in block scheduling). That’s the current class I’m in, and I really don’t like it that much. It’s super easy for me, but I don’t feel like I’d be motivated enough to learn more advanced grammar concepts. In addition, I’m also in Spanish V and I’m starting to confuse the two languages. My teacher, who speaks both, is encouraging me to continue with French, but I don’t want to have too much on my plate. Next year I plan on taking AP U.S. History, AP Lang, Pre-Calculus, Human Body Systems, Physics, Spanish V, and Mandarin I (I will be a junior). I planning on majoring in Linguistics in college, but I’m not sure which is the smartest move for me. Any help is appreciated!
