Congrats! I worked in a call center for several years. It was really helpful to improve and maintain my fluency. Bianca... Do you block on the beginning of your name? When your lips come together to form the B sound? I'm going to assume that's where you block... Try keeping your breath flowing out while you say your name, and do the B sound as softly as possible. Specifically, make sure that your lips don't fully close on the B. That air flow continues before, during, and past the B sound. It's going to sound a bit off to you at first. That's fine though. Practice it a little and seek a familiarity with this approach to saying your name. Remember that you listen to your speech much closed than anyone else is listening to your speech. No one else will realize what you're doing.
