I recommend you stop transmapping languages; instead, learn each on it's own, mapping it only to your own mental meaning. Second that. I spent a year in Japan, and got to the point where I could have fairly comfortable conversations, even in both languages if you were at a party with both native speakers. What really stressed out the mental faculties was having to translate, because you had to do the whole mental re-mapping, which you didn't have to go through for a single-language conversation (or even for two separate conversations in different languages).
