On those days when we feel overwhelmed and sad, we have to find a way to break ourselves free. We have to push ourselves to action or the hole we dug for ourselves will only get deeper.
When we feel like this it can be hard to find the energy to do anything. All we can do is start small, go for a walk, create something, read. Find something to do, something to distract, something to change were our heads are at.
Once we do this we can't allow ourselves to fall back into stress and worry. We can't live where we wallow in despair.
