If it's not one thing, it's another!

Many unfortunate, stressful things keep happening in quick succession. First the power goes out, now the printer isn't working—I tell you, if it's not one thing, it's another! If it's not one thing, it's another this year, between losing my job, breaking my ankle, and having the basement flooded. The car won't start, and now I can't find my phone to call a tow truck! Geez, if it's not one thing, it's another!
