I have been talking a fair amount lately about acceptance of your situation as a way to mentally deal with a prolonged stressful situation. I also admitted I am not doing well at taking my own advice, so if it's not working it's time to find a different approach.
"If you can't change the situation, change the way you look at it." To steal a piece of paraphrased advice from Wayne Dyer (spelling?). For the last day or two instead of simply accepting what I cannot change, instead of having to deal with a troubling situation, I started asking what lesson is Life/God/the universe/(... ect.) trying to teach me (or as I'm starting to feel -- shove down my throat)?
I don't have an answer, but pondering this has calmed me somewhat. It's almost like pondering a koan, although in this case unlike a koan I think the answer, if I figure it out, will have as much value as the striving for the answer.
We all have our share of ineffable knowledge that we simply cannot put into words and at best can only give others subtle hints that they either get or they don't about this esoteric knowledge. I have a feeling the lesson I am meant to learn will be of that type that.
