I had problems with depression as far back as early childhood, which leads me to believe that, for me at least, it is a chemical imbalance. I didn't seek help until my own son began experiencing the same symptoms. I knew what he'd be going through and I couldn't bear the thought. That gave me the courage to get treatment for my own depression as well.
Fortunately, we found the right medication after just a few tries, and, in our cases, it really was truly miraculous. It even made a huge difference in my socially crippling shyness.
My son stayed on the medication from age four or five (yes, astonishingly young, I know, but it was very severe) to age fifteen. We were able to wean him off of it at that time, and (crossing fingers) he has never needed it since. (Another miracle)
I think because I was older and my brain had already formed and made connections and learned patterns, I continue to need the medication, but it continues to control my depression as long as I take it. I still have mild depression on occasion, of course, but it is temporary and normal and based on life circumstances, not that overwhelming, desolate, black hole of hopelessness and despair I lived in most of my life.
I am a big fan of antidepressants in the right circumstances. I don't think they're to be given lightly, and I do believe some depression is necessary and normal and even required if we are to develop into sympathetic, caring, well-rounded adults. Pain and sadness are an important part of life, and it is important that everyone experience them.
But, when pain and sadness take over a life, then I become a huge fan. It sounds to me like that is what has happened to you. I hope you feel better soon.
