Done with college

Hi guys, I haven’t used this website in a year and I don’t know where to put this but I just want to get something off of my chest.
So recently I finished my second midterm exam for Precalculus. After realizing I got a 59 on my first exam (I was sick, so coming in then I couldn’t really concentrate that well), I decided that I would study for a week before my second midterm exam (which I finished a few days ago). All seemed relatively understandable and the problems on Cengage were perfectly clear to me. When I took the second exam however, I ended up failing with a 56. Half the questions were just nonsense in my head, and I feel like I wasted time doing nothing.
I feel stupid and I went through a bit of a fight with myself - I’m mostly upset by the fact that if I fail Precalculus, I will have to take it again and delay my graduation plan. I feel hopeless at the moment. I’ve already changed majors to ease the workload for next year (I changed from Computer Science to Biology, which I personally enjoy more), and I still feel stupid as hell. It just feels like everyone else is doing perfectly fine and I’m nowhere near progress. This isn’t the only class I’m failing too; I’m taking another class called Programming in C (it’s a fun class, but the projects are so difficult, and the help/tutoring is plain awful). I think this year overall took a U-turn quick; everything in my first semester was fine, and then midway through second semester and suddenly everything takes a downward spiral.
I don’t have a clear question to ask, but I guess all I really need is some advice. I just don’t know if college is worth it (or if, at least, what I’m studying is right for me). Has anyone else failed precalculus in college? Has anyone else been through similar struggles? I may be overthinking it now, but it’s not easy bottling up failure like this; I really just needed to type this up.

For context, I am a freshman. (I’m not saying where I go).

@stephjkla My definition of success is to push yourself to the point of failure. Without doing that how would you ever know what you can accomplish?

Does it have to be all or nothing? Maybe you’re in the wrong major.

Are you at an OOS college? If costs are an issue you may want to consider transferring to an in state school. It’s easier to concentrate if you’re not worrying about money.

I think math is something you might have to work at every day, not just study a week before the exam. If you’re going to need calculus I think I’d focus on other courses for a semester and work on your math skills.

What are you planning to do with a degree in biology?
