I don't regret it at all that I stayed at home today, even if I have to write two tests next week.
I just took a warm bubble bath and in some way I think that helped? I feel much better now, I'm not even so tired anymore. It's so relaxing, and I love the bubbles!
Soon we'll have a bubblepool in our house, when our bathroom renovation is done :D But it's going to be just a small one.
