Depressed????

The past two years of my life have been the best ever with a few exceptions, I am a creative person through to my soul. Decoration, is a passion, but this year it’s gone? I have a beautiful home, a loving amazing husband, so what’s wrong with me? I look at all my decorations and just don’t feel like putting them up. Yes,I am stressed, my house is always turned upside down with remodeling, I have half a kitchen, no doors on the cabinets or drawers but the rest is done. I have shoes and pillows piled up on shelves cause my dog won’t stop chewing them, although I know he does it to get attention, which I am not giving him? I don’t feel like Christmas. I don’t know were It is but, it is not here, not inside me. I had cut back two of my depression meds in the past 6 months, could that be it? I was put on Prozac at 18. I took 40 mil till I was about 30. Then they said,it’s not working anymore, I started cymbalta, I was on 60 for mental then on 30 for pain. I also take webutrin, was on 300, cut back to 150. But now, I don’t know what is wrong with me?
