If you overslept - then you needed the sleep! Emmie is quite right. The only way to cope with these things is to llaugh about them. It's usually later that you chuckle, though. I'm not laughing at the mo. because Mr. J2 peeled off a ladder getting into the loft on Tues. aft. and I honestly thought he'd killed himself when (after the yell, thuds and crashing noises) I found him crumpled at the foot of the stairs. However, wry smiles are already appearing and once he is fully recovered I'll find something to laugh about.
You're being brave and capable, but please think of your own health and take care to give yourself bits of treats and time-out. I know how exhausted I felt yesterday with all the stress, picking up today after an outing just doing the shopping and a bit of a wander around. It must be far worse for you. :) xx
