Introducing myself

Hi, I'm Mariana and I'm 21 years old. I live in Brazil and I love traveling. Since I was a child I loved the English language so much that I always asked my parents to put me in the english course. Unfortunately we didn't have much money to pay for a course. But when I was a teenager my mother said that I was at an english course. I loved it so much, and since then I have searched everywhere, for me to learn more and more. I stopped 3 years ago and have forgotten some things, but now I want to practice and get fluent. Anyone who helps me I'd be glad.

This isn't wrong per say but it a suggestion would be

I always asked my parents to enrole me into an English course.

Well done, it was really good.
