Is there a specific part of a natal chart (birth chart) that shows whether someone is prone to depression?

Its usually bad aspected Saturn in the 1st house (you),6th house or 12th house (health/mental health) or Saturn in bad aspect to your personal planets (Sun,Moon,Mercury,Venus,Mars plus ascendant). Also having aflicted Neptune and bad aspected/lots of planets in water signs (they are very sensitive,with sensitive nerves,prone to depression).

Your Moon in Virgo, (self-criticism, lacking in confidence) is conjunct Chiron, (emotional insecurity, extremely open to outside influences or interference); Chiron itself here can bring "wounds" that come about because of self-criticism and the search for perfection, resulting in mental or nervous disorders. Healing here comes from being of service to others, on a one to one basis. If that's not enough, your Moon is opposed by your Pisces Saturn, Mercury and Mars; Chiron opposes your Saturn and Mercury.

All this is quite heavy to put it mildly but you do have some help from your Moon to Jupiter mild harmony and your strong harmony from Jupiter to your Mars, Mercury and Saturn. You should be strong-minded with a flair for research, hence this question; you "can" be optimistic, passionate and strong, you should be able to bring about things or events that you need. Your innate wisdom should be really beneficial for you as you can learn from events well; or at least are prepared to listen to other people's advice.

You have a strong intellect, especially in presenting yourself to others, (no planets in air signs but your ascendant is, in Aquarius). Your Sun is in harmony with Pluto so you definitely "can" transform yourself in ways that are necessary to your well-being.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
