Medical assistant

How much do you guys make as medical assistants? If there are any on here. And what part of the world do you live in? I've really put thought into it and have decided it is what I want to do. I went to cosmetology school and it wasn't my thing, I unfortunately didn't finish. Then for awhile I was thinking about just getting my CNA but honestly that isn't the type of work I want to do. I know MA's are kind of similar to CNAS but from my knowledge not really. I'm just scared I'm not smart enough to get through school..I'm 22 and graduated high school in 2010. I don't remember anything! I was really bad at science and math and those are things you really have to know to be a MA! I'm nervous.
