I have trouble keeping my emotions in check. Lately, I have been able to stop myself when I start to feel upset.

But people around me always notice how sad I look. I might be feeling okay, but a brief moment of sadness leaves my face looking pretty sullen. It's hard for me to hide the sadness in my face. I feel like this is a problem because it leads my friends & partner to believe I'm sad when I'm just pushing through my emotions.

How do you deal with this? Is there something I can tell people when they ask me if I'm sad?
