do you let everyone know that you're not in a good mood or feeling well so that they'll leave you alone? Do you let it influence your performance at school or work?
I've found that too many people expect others to leave them alone or avoid certain topics if their days are not going well and expect all of this attention from everyone so that they can feel better about themselves and about their days. When they're the ones having a bad day, anyone else's bad day doesn't seem to matter.
For example, let's say that my girlfriend wasn't feeling well because she was having problems with her room mate. Let's also say that I wasn't having a good day because my email was acting up and I couldn't check to see the details of an appointment I had. If Jessica expected me to understand her troubles and be supportive but she didn't care about my frustrations with a meeting I missed, I'd be disappointed because it would seem like things going on in her life were the only things that mattered to her.
If I'm not having a good day or not feeling well, people usually can't tell. In my experience, letting others know about it at school or work means your performance suffers and you can't get things done when you have assignments, projects, and other responsibilities. People out there expect you to keep it under control so you can still meet deadlines and finish what you started.
