in the USA, it is assumed that your parents pay for your college.
So you can decide to major in something acceptable to them or to find a way to pay for college yourself.
i am an engineer and I took AP Calc AB in HS and then took Calc 1 again in college and did just fine as an engineer.
I work in telecom as an analyst/solution architect which is not a detailed hands on job.
In your case I would pursue Environmental Engineering with Poli Sci electives.
Get tutors/go to Professor office hours if you need help.
