It's just a chemical imbalance in your brain. Anxiety is caused by too much dopamine. Eight years ago, when I started taking Zoloft, my doctor at the time told me SSRI's help regulate those levels. I definitely can see that that much has happened. As far as the depression goes though, not sure if it's helped much.
