time to take advantage of your existence

I'm curious what you mean by existential depression/angst.......?
It's a pretty wide open term.

I don't understand the existential part, otherwise, yes.

Yeah. I think an educational system made up of general education contributed to a major upset about not answering my personal questions on mathematics, machinery, programming, the body, the arts, language, and such.

However, there was always a physical and/or lifestyle cause of my emotions. Medical science is pretty supportive of that conclusion; basically every mental illness has a component that corresponds with the health of the body.

Absolutely! Wish I had something encouraging to say, other than “I’m right there with ya.”
