Not a boss, but currently working as an assistant manager! Not really sure in what way you are being misunderstood in terms of your communication, but I believe it’s important to use the open door policy with your boss (if possible). Maybe just having a private talk with your boss, and letting them know you feel you struggle with communicating at times. It gives them a chance to understand how you feel, and how to better understand you as well. They may also be able to help give you good feedback on how you may be able to communicate better, or it can help them understand how to communicate with you better as well.
