I have noticed a bad habit lately:

I'll have a relatively good day at work, no big mishaps. But then on my drive home or while I'm relaxing at home, I'll get a sudden feeling of dread, like I've been punched in the solar plexus, accompanied by a thought like "omg did I forget to do X??" or "oh no, what if I messed up Z??" And then I spend the entire evening agonizing about it. My stomach is in knots, I can't sleep, I can't eat.

This has happened a few times in the past few months, and not once has my worry been true. I'm not sure where these irrational worries are coming from, they come on so suddenly and I become entirely fixated on them, and I vividly imagine the worst-case scenario. Attempts to reason with myself or distract myself are futile.

I don't know what to do. Have you experienced this? Why is this happening? Do you have any advice?

Thank you.
