Update - I've been feeling pretty mellow the last few days, which is a big relief, since this is coming on the heels of some very bad depressed days.

I think what has made the difference has been going on regular hikes in Sedona with a friend, and phoning/texting my mother. It also helps that I now have a real solid plan for where I will be living, and that I will finally be seeing my husband again for a few months, after a really long absence.
