That seems like a questionable reason to ditch CS to me. Was it really that bad to do the technical writing courses?

Yes, having done all kinds of styles, I can see wanting to avoid technical writing. It's a highly rigid form, with lots of rules about how to arrange information. Sometimes just the tools are enough to make you want to quit: I'm looking at you (La)TeX.

Thanks for questioning my reasons (anonymously).

As such things tend to be, it was the last straw. I was an angry, shy, lonely young person. I didn't know it at the time, but I was 1 year in to 6 years of ~writing-my-way-out of the worst two of those.

I came to school thinking I'd study writing or programming. I started with the one likely to pay more to please my dad, but only found one of the intro CS projects remotely engaging.

Yes; we were sitting in technical writing (second semester) discussing what we'd done for the first assignment and why. Through the lens of the only thing that I really found engaging (and catharctic, and joyful) in high school, I could see that my heart wasn't in it. Any of it.

(I would later return to programming through art projects.)
