Luckily robins have very small brains and likely do not have the ability to feel depression or emotions of any kind.
If learning to be grateful and to "live in the moment" was all it took to cure major depression I believe most people would be cured by now. It just isn't that easy unfortunately. When you have a family history of depression, obviously genetic, where 4 relatives (that I know of) have committed suicide and many others struggle each day just to keep going...anti-depressants help, exercise helps, having loved ones around help but a sense of well being and real happiness may not be possible for some.
