I would like to know what lies you guys tell to keep the people around you from get tired of/mad at you for being anxious or sad all of the time.

For instance, sometimes I will start crying at work if I mess something up or get too overwhelmed. I feel like an idiot when I cry while I'm waiting on people , so if they notice or ask me what's wrong, I will just tell them I have allergies.

It is harder to fool my husband at home though, and I would like to learn how to get better at faking it. What lies do you tell to get through the day without then having to deal with the added stress that you're bumming everyone around you out?
