I'm still not convinced learning a 2 language is harder, even as an adult. I now know 3 and if you put some effort and time (or even better get immersed) you will learn it. Children have YEARS of amazing immersion, adult patience and care. Who wouldn't learn a language in such fertiile conditions.

As for the accent which i have, i don't know yet. I will try to correct it and see how it goes.

The step from one language to two is much, much larger than the step from two to three or beyond. I did this seriously for the first time when I was 21/22, and it was initially difficult to get used to the concept of thinking not in terms of the temporal order in which words are introduced (i.e. the syntax of the language in which you are speaking) or at least shifting your process to generate sentences on the fly in a new order. In my experience (native English, learned German) I had a relatively smooth transition but even so it was difficult not to construct sentences as I spoke in the typical English construction. Once you get comfortable with shutting off that reflex to formulate thoughts according to the syntax and vocabulary of your own language, learning language becomes a lot smoother. This reflex is of course more strongly burned-in the older one gets due to the decrease in neuroplasticity as we age.
