Brain fart or cascading malfunction due to mental illness(es)?

Yesterday I'm at the restaurant. The waitress brings me a large glass of unsweet tea. I set it down next to the ashtray and reach for the Sweet-N-Low.

I tear open the two packages of Sweet-N-Low and begin pouring them into the tea.

Except it's not the tea I'm pouring them into.

It's the ashtray.

They are half empty before I realize what I am doing. And yes, I was looking the whole time.

This is the problem with having a (self-diagnosed) mental illness -- you don't know when a goof is a brain fart like everyone has and when it's a symptom of a progressively-worsening disease.

In the end, I don't guess it matters, since I have no health insurance and couldn't do anything about it if it IS a new manifestation of my brain errors.

I just wish my brain problems would either go away or get bad enough that I no longer have the ability to notice them. They are embarrassing.
