Yup, you better communicate than not to. Utilize every source in terms of reaching out to natives: no matter be it text messages, be it audio/video, be it face to face, which is lit and at times unavailable, y’know.
As time goes, you will gradually get to understand everything. Rome was not built in a day...
UPD: I skipped the point where you doubted if natives would have understood ya. Go ahead. They will get you either way.
