I smile under stress, when I am nervous or scared. People always tell me I must be an extremely happy person because I am smiling all the time, but Iâ€™m not. My cousin was in a car accident a few months ago. When my mom got home I told her and it took me a half hour to convince her it wasnâ€™t a joke. She thought I was kidding because I had a huge grin on my face. I felt horrible! And that wasnt the frist or the last time it happened either. I just want to it stop, but I feel like I have no control. It is not that I donâ€™t care or am happy about the stuff I am â€œsmilingâ€ about. Please help.
