Things get super stressful sometimes.
This is not profound nor actual news to anyone I know. It is a fact of life though. I hate it. I'm outgoing and mostly upbeat naturally so it takes a lot to bring me down so I know it's time to step back and reevaluate how to improve less than stellar zen like happy days.
What I do when stressful moments happen to happen:
Meditating mojo- I've gotten into breathing practices to bring me back to earth and the present moment during stressed out times. Simple, in the nose-out the mouth, about 5 sets usually does the trick. I learned this in therapy years ago and honestly I'm all about the natural way to alleviate angst.
Lemony water- Good ol' hot agua made in my regular ol' kettle teapot. I don't know if it's the soothing warmth or the tart wake up call but this one will set your britches on right.
Walk it out-when possible I will get lost in a brisk pace, be it 20 minutes or 2 hours. Both durations help and offer their respective calming effects. The other day was super stressful and I managed to snag some time for me. Before I knew it, I covered 5 miles of terrain and felt completely rejuvenated.
I hope you regularly soar more than you struggle. Days and years are short so keep it all in perspective and do self check ins often to prevent burnout and turmoil.
