You Should Take Some Deep Breaths
Part of what's stressing you out right now is that there's too much going on at once. You hardly have room to breathe.
And to be honest, the idea of taking on a little project to de-stress yourself is even stressful.
So don't worry about doing much. Just take a few deep breaths. In fact, try it right now.
Doesn't that feel good? Repeat this as often as you need to. This is the first step to clearing your head and feeling better.
