Being misunderstood is disrupting my life.
I have been misunderstood many times, but it wasn't a big deal to me because either I didn't know about it or it just didn't impact me seriously. But it is starting to disrupt my life. For example, I work as a tutor and my boss told me one day that I look like I don't even want to be there. This was not true at all. I enjoy my job and look forward to it most of the time, and it hurts that I could not display that properly. She said I didn't look happy, but it was just my resting face. This wouldn't bother me much in other contexts, but this is my boss so it affects me seriously. Another example is my driving instructor who told my mother that I didn't seem like I actually wanted to drive because I didn't seem happy, wouldn't talk much, and would be serious. But that's not at all true because I actually enjoy driving, and because of this my mother is upset with me because I told her I wanted to learn. Other times my friends have told me that I don't seem to care about them because I don't cry when they are sad or seem empathetic towards them. Which I do really care about my friends, and want to help them the best I can. This problem is negatively affecting my life to a greater extent than I am comfortable with. I genuinely don't know how to solve this. Please share any similar experiences, advice, suggestions, anything helpful is appreciated.
Tl;dr: My neutral expression and personality is causing serious distress in my life. And I don't know how I should improve this so I can properly convey what I feel and limit misunderstandings when they severely affect my life.
