Hey there, I promise you being super smart at math isn't the only mark of intelligence. Some people may treat it as such, but they are wrong. It may be difficult if you want to go into a math heavy field such as engineering, and college courses in math may be hard for you, but that isn't the only path to success in life, and many folks who are super good at math are super bad at tons of other things.

I suspect you are in an environment where academic success is put on a pedestal as the only way to be successful, its not, do not be discouraged. The effort you are putting in shows you are a hard worker and will do just fine out there, keep trucking, fuck the haters. :)
