You don’t have to declare a major right away, plus you can always change your major. But remember you are eventually going to have to work in a field, for a very long time (the majority of your life.) How much better to love life in part because you love going to work, rather than waking up in dread every day because you have to go to a job you hate. You can make a good living in all the fields you mentioned. Just get tutors (many colleges have free assistance,) ask your professor to further explain what you don’t understand, get study buddies. Math and accounting aren’t so much easier than the other three subjects you mentioned, either, so if you can do them, you can do the others. And remember, you don’t have to be a straight A student, you just have to pass. So go for it. The more involved you are in the subject, the more you’ll learn, the more you’ll know, the more intuitive it will become, and you will succeed. Perseverence is important. Good luck.
