Flashes of feeling sad and alone

You don't have to tell me if I'm right or wrong, but I am just guessing that your parents never (or rarely) showed you any physical affection.

Considering the question, I figured any answer was better than none.

Anna- it’s called a “pause” and is nothing to worry about, unless others tell you that you are staring for some time.

You can ask your Dr. about mini seizures.

I honestly had a perfect childhood, my parents did show me affection. But I did talk to my psychiatrist and she said I probably had separation anxiety, which I don’t really understand.

That was just a guess, and I didn't want you to feel alone. Even for a moment.

Just remember that the next time...

If you mean you don't understand why you would have separation anxiety, (if that is what it is), it could be anything. Losing a close family member when you were a child. Childhood friend moving away. Getting lost in a store when you were a child. Even waking up in the middle of the night as a very young child and not knowing where your parents were.
