I empathize too! Lots of stuff on my plate right now, some of it pretty darn big.
I heard an analogy in a meeting yesterday. Air traffic control lands one plane at a time. It proceeds to the hanger, and another one lands, and so on. Sometimes there are a lot of planes in line, backed up on the runway. They still have to proceed one at a time in the right direction.
That was a good visual for me- and I've been remembering lately that with the big (like a stepson maybe finally accepting he needs to go into a year long residential treatment place) and the small, that they are indeed all first world sober person problems and I (and my husband and I) are equipped to handle them- and know that it will be OK.
