plm,
I struggle with clinical depression that has a tendency to swing lower depending on my hormones and other things happening in my life. The depression became critical when I first became inactive; I believe many of the separation issues I was experiencing (plus all the other "stuff" my heart and mind was going through when I began my journey away from a lifetime of core beliefs) contributed greatly to my depressive and suicidal state.
I was on drug therapy for about 2 1/2 years (Zoloft mostly, Prozac & Lithium when they *thought* it was bipolar) during this time and weaned myself off when I felt I was ready to. Since then I have managed without prescribed medication, although it has been difficult at times. I do take a supplement called 5-Hydroxytryptophan (5-HTP) when I feel I need it to balance out. It works well for me in the dosage I take; I'm on it for probably about 6 months out of a year.
The other things I agree with have been mentioned: exercise and diet. I find that I do feel much better when I'm exercising and eating right along with the supplement. Plenty of rest and activities *other* then being online too much help also.
I hope you find the right combination of therapy and activities to help balance you out too. It would be nice if it just cured itself and went away, but those of us who deal with a chemical imbalance that follows us around year after year know better.
Wishing you and the others an even-keel,
Kristen
