Yes, totally. It's a lengthy commitment to learn any new language to the point where you can fluently speak it. I've had many times where I am afraid to fail at becoming fluent at a language and think that I had wasted all my time and energy to learn an incomplete skill. I still get these thoughts sometimes, but there's a certain point where you've done everything you can, and the rest just has to be experience and practice, sometimes in a different country. By the sound of it, you'll do fine. You're learning two languages simultaneously, that's pretty impressive.
