MATHS

I've always had an interest in science and becoming a scientist has always been a dream of mine. My problem seems to be my lack of math ability. In high school I took algebra and pre-calc and did well but never dared go any farther due to fear of failure.I feel like I should start learning math from the very basics again. Maybe I just didn't get it as a child. Anyone here like me? I'd like to become a scientist and contribute to society but I'm afraid I won't be able to due to my math inadequacies. How would I go about self-studying math?
