Oh, gyneco, I know what that's like. I'm trying to learn 3 languages right now, and it's hell on the fragile ego, I know. I'm just starting to become comfortable and at home in German, but I dread having to speak Arabic, my not-so-nice roommate who's also taking Arabic has made me feel terribly embarrassed about my accent (which admittedly is really, really thick). This Sunday I'm going to a Lebanese church to practice, my goodness I get so nervous before hand. It's tough, and I know you've heard it before but: you just have to practice it. It doesn't matter if what you say is stupid, just so long as it makes sense. Trust me, English native speakers say the dumbest nonsense all of the time.
Where do you come from? What's your mother tongue (I guess Greek)?
