(((garden gal)))
Yes, I have those dang mood swings

They are maddening!
The trick, for me, has been to put more positive activities in my days. This keeps me leaning more towards the positive side of life ~ rather than my old "usual" (negative). My big help in those negative dark times is to put my energy into exercise. Put on my iPod, go to the Y, and work all of my anger & energy out there. I have workout videos, but they don't work nearly as well for me. Walking out in nature is also a wonderful relief for me. Nature almost always brings me peace & puts me in a better state of mind. Sometimes, I can't muster up the energy (when I'm low in the funk) to go. Then I bake something, cut it up into small pieces and put it out for others to enjoy. (I live in an apartment building)
Gentle hugs to you gal ~ you're in my thoughts!
