just a thought and I offer my apology in advance for being nosy...
when you have your physical next week. your physician should run blood work--CBC--but ask him/her to make sure your thyroid hormones are within normal range and so is your sed rate. if it's a fasting blood test, then your blood sugar level can also be checked...
jmo/jme, but there are many physical problems that can cause or worsen depression and energy levels. it just seems safer to rule out these possibilities before any med adjustment--if you are on meds.
that's another thought...if you have started any new meds or had any adjusted, it might be worth it to look at that, also.

sorry if I stepped on your toes...
