CM being worn out can be expected. Nothing wrong with a little pity party now and then, especially for a tough-butt woman that tries to do it all. (I don't know about you, but that is a luxury that I fight so hard against, but probably should allow it to happen more often.) This might be too simple of a thought, BUT, have you tried increasing your vitamin D? It helps me during the winter months, and really gives me much needed energy. The only thing I have found annoying is that it can make me a little hyper. (Well, actually that's an improvement over wanting to sleep every afternoon.)
