Is Anxiety And Depression Pyschological Or Physiological?

Is your anxiety or depression all in your head? Is it just the result of bad thinking patterns in your mind? Or is it the result of something going wrong inside your body? I'm going to talk about my journey with anxiety and being told I was simply suffering from panic attacks when in reality I had a major serotonin and stress hormone regulation problem that nobody guessed at until I did my own research. If you suffer from a lot of stress, or you find yourself becoming frequently neurotic - perhaps it's not all in your head after all - and perhaps there's a very reasonable solution to the problem. Doctors don't always know the answers, and it helps everyone to go and become their own researchers to find the solutions.
