Eh, we all have days like that, right? No point moping and sulking about it though. Too much to do. So, like a lot of people, I take steps to get over it. Occasionally, besides deep breathes and premeditated exercises in perspective, I'll also get a sign that everything is still just fine.
In the form of rainbows. Not always in the sky either. In fact, as I age, the sky type seem to come less and less frequently but, the indoor types seem to get more so. I see them on the ceiling, on the walls, on the floor, in the sink... no prisms necessary!
This last one came to me in the bathroom sink. There are these great blocks in the window that refract light - if it hits at just the right angle - into wonderful rainbows all over the place. I see the rainbows, stop, and everything seems much better.
