Math only becomes a "skill" just like any other so as long as you work at it. If you put as much time studying math as you do arguing online, you wouldn't think yourself so unskilled.
When I was 17, I had only Algebra II under my belt. Instead of taking courses, I decided to devote my time and energy towards self-study eventually testing out of Calculus I at my college (they allowed me to take Calc.II instead). You can choose to envelope yourself in a "perception" of a drawback or choose to give it a good try and study to see whether you are good or not.
