I could be wrong, but
I don't believe you overcome depression
I think you learn to ignore it.
Here's your situation, astrologically. Look at your chart.
You have a Grand Cross in Fixed signs composed of 5 planets. This difficult cross resides within, quite typically, a Splash or diffuse pattern of planetary distribution. The person born under this configuration typically "gets on his horse and rides off in all directions at once." It suggests widely divergent interests and relationships without any particular focus. This can result in indecisiveness or a pointless sense of drifting...or in a striking ability to bring differing elements into an organized whole with self at center.
When the Fixed quality is preponderant, as it is in your chart, it suggests a lifelong struggle to attain internal psychological balance. There is a sort of detachment from external events of themselves and instead the native focuses on the meaning or significance of the event and how it relates to the self. You can learn a lot about the Fixed quality by looking up the word fix and its derivatives in your dictionary.
The grand cross is a complex aspect formation involving 4 or more planets and signs. It is formed by 2 oppositions and 4 squares. It forms a box.
And it boxes you in. No matter which way you turn you are blocked. There seems to be no way out. This condition tends to be long lasting, usually at least until the first Saturn return.
You can fight it, but you won't win. Or you can learn to live with it and use it.
