I think this is a good answer, but depression is a complicated beast. It would be difficult to give a comprehensive comment in depression, so I think you did fine, but I want to point out that it is difficult and complex, and as much as we understand about it, there is so much that is not understood. This [1] is a video of a Robert Sapolsky lecture on depression that gives a high level but comprehensive overview of the current (as of 2009) state of understanding depression, kinds of depression, the role of some neurotransmitters. This is a compassionate, technical, and broad overview. 1. https://youtu.be/NOAgplgTxfc https://youtu.be/NOAgplgTxfc
