Whatever the offending situation is, just take a break from it. Naturally and inevitably you will cool down over time. You can then choose to return, or not. Either way, there is nothing to be gained by a public announcement.
I found public announcements of people leaving Xitter to be very useful, because they were coming from people I respected and was interested in hearing from. They also served as a frequent reminder that the site had, in fact, become a Nazi Bar awash in every type of far-right disinformation, lies, and manipulation possible, fully supported by the site's owner. I was glad to finally leave permanently after seeing too many people I respected do the same. The Fediverse is far better.
