I've been comtemplating entering a note like this for a while. I understand I could be entering dangerous territory. I'm an amateur homeopath and have more than a passing knowledge of it. For more information check out the National Center for Homeopathy
The good news is there is relief when the right remedy is taken. The bad news is there are thousands of remedies. Here is a partial list of potential sadness remedies: Aurum Metalicum: Suicidal - wants to jump from height. No hope. If you're here you really ought to be seeing a professional. Ignatia: You can't accept a situation. Hysterical. Good for after spouse "drops the bomb." crying. Phos. Ac.: Pining away for someone. Exhausted from yearning. Veratrum Album: Sadness from "disappointed love" and your blood "runs cold." Like ice water going through your veins. Staphasagria: Often from being violated. Can take on a sexual expression with an "edge." If suicidal wants to shoot self.
There are dozens of other remedies that can fix saddness. If you're just a little blue, deal with it. Don't take a remedy unless it really fits you. Your state of mind can change and with it the appropriate remedy for you. You can get many of these remedies by ordering them through your natural food store or 1-800-DOLISOS (2 dram, 30c)(shipping charges will kill you ) Only take homeopathic preperations of these as the crude form can often harm you.
Better yet, see a real homeopath. See the link above for finding one.
It's made my life and my dealing with my situation much much easier.
