A post on Twitter

I have struggled and endured. It was a tough month with apps and work and school. I withdraw from Bio, and need to take care of Kumiko more.

"twitter" may have been preceded, etymologically, by "twit".

"twit" (noun) An insignificant or bothersome person (orig. 1920-25) "twit" (noun) To taunt, tease, reproach

Either would seem appropriate.
