Ya, what Clovermom said! I think self affirmation mantra's, weather you believe what you're saying or not, can be potentially helpful if you use them enough.
I also have several guided imagery CD's that help me too. I tend to have a wondering mind, and in times of weakness, I find listing to someone suggesting to me what to think about, helps me to focus and calm down.
Failing that, homeopathy helps me too.
I find hormones don't necessary help my ability to think rationally.
I guess much of it for me comes down to just training my brain to cope. Not all that happens will be good, or bad. Bad will happen, but I can handle my reaction to it. I believe that if I live long enough, my life will, somehow, balance out. And that as many horrible, devastating things that have happened to me, I have had amazingly good stuff happen too. I try to focus on that when bad stuff is beginning to happen. I figure if I just hold on, I will have a time of peace and happiness again.
I have you in my thoughts and prayers Bluebird.
