Some on here may have needed this, but if people's mood gets low enough, the 15 minute rule is a common way to help with motivation.
Whether it's something seen as work, such as housework, or taking time out from work, the 15 minutes feels more possible than the whole activity so, eventually, you are likely to continue. Of course, that can take time, and some may need medical help too. Others may be able to use it for themselves or join something like Fairycakesdid.
It sounds as if most on the thread are one of the lucky ones who have never plumbed these depths of depression or anxiety so that it disabled them in this way.
What was your happiest moment today?
