Learning Latin is like learning maths. There is a lot of difference between learning a dead language or a living one. With living languages you'll learn not only grammar, but present-day matters, but with Latin you'll learn grammar and surely soon you'll translate from Latin to English.
I studied Latin, Greek, French, English and, of course, Spanish grammar at the same time and I had no problem. Anyway, as Perikles said, I was a teenager then.
