I absolutely agree!

If I don't feel up to seeing my family or friends, I usually tell them that I have a migraine. I do get migraines, but not as often as I tell them. I understand also about feeling guilty about not telling them the truth. I view it as self preservation. Like you, I need time to myself and I like my privacy. If I decide to share any personal information, such as who I'm dating, etc. that is on my time table, not theirs. My family is full of extraverts and I am one of the few introverts. Most people do not understand me but I am trying not to let that bother me. I like who I am, for the most part.

Glad that you were able to talk to your mother about depression. Maybe she will educate herself on it.
