What does it mean to fuss too much?
It can vary depending on context it is used, but it can mean to figit or worry too much, to be aggitated, to place too much attention upon... usually if someone says your fussing too much it means chill out and don't worry about it
when you bug, bother, nag, pesture, annoy. :) Merry Christmas.
exactly how it sounds
That means to show unnecessary concern or whine over something that doesn't matter.
