I've suffered from chronic depression and chronic mild anxiety all my life. I've been on and off zoloft and hospitalized twice. Here's some ideas for holistic stuff. Some may work, some won't. I find that it helps most of the time.
1. Make sure you're getting enough sleep. I know as a mom that's impossible, but schedule it. You need 7-8 hours. And no more. Sleep helps regulate seratonin levels.
2. If you're not working, you can try to get outside for an hour or so around 12-1. The sunlight and exercise can help.
3. Take a multi-vitamin. Make sure you're getting enough Bs and Folic Acid. Honestly, I take chewable Flintstones vitamins :)
4. Fish Oil has been shown to help regulate brain function and may help with depression. But this usually takes a week or two before it truely helps.
I really hope that one of these helps you. Remember HALT. Don't let yourself get too Hungry, Angry, Lonely, or Tired. Take care of yourself!
