Yeah, I'm multilingual from a hispanic country, and due to job experience and the media I consume I've ended up with a real mess of both accent and lexicon. Nowadays, most of my english and italian interactions are limited to online gaming, and half the time people catch on to my accent, and guess I'm either quebecois, german, or french, despite not being fluent in any of those or ever spending more than a week in any of those countries.

In day to day life, I mix all three (spanish, english, and italian), using the first word that comes to mind. It feels really jarring trying to convey a complete idea in just spanish, and end up translating foreign words in my head. It's faster for me now to communicate in english than it is in spanish.
