I'm glad he is on medication, as it helps to smooth out the moods a bit when they are.  jess is also, on some type of medication.

This woman, whose chart I just posted on this new link, never took any type of medications......although she was diagnosed with mood disorders, and even schizophrenia, feeling everyone was against her.

 

What I noticed, between her chart, your brothers, and Jessica's, is that all 3 of them have Mercury Retrograde natally.

 

This is said to be a sign that in the past lifetimes, these people may have carried in with them now, a  propensity towards, thinking that is never progressive,but always, more "retarding" in that it thinks in reverse, of the past injustices,  hurts, etc.

 

Not people to think of the "Day" or moment, tending more towards reactionary behavior or "past" tense .,which is something that eventually can harm them and other around them who can then be seen as "evidence of past" type of things they keep thinking and rehearsing in the past tense.

 

I think it is more then possible that many with various mental and emotional disturbances do have a Mercury RX (not all) but many who live this way.

 

These then, are only 3 examples.

 

 

 

 

What is happening  with him now, according to the transits, it appears to be that the BML transiting over his natal Moon & Neptune, brings up again, "things from the past", not unlike with your own natal now.

But for him, BML is also with progressed Venus, so affecting his home life and wife.

Surely his Moon conj. Neptune so very close (within one hour) when born, makes him suseptible to illusions or even delusions from the emotional realm (the moon)

 

With the 9th house cusp in Virgo, he sees his mother as controlling, nitpicky &^ manipulating, as he also sees his father, that way too.

 

Saturn now over his natal BML (leaving this position , so therefore, the relief that the worse is over now).....and instead Saturn is now positioned over his natal Mars.....on it's way to the Sun.

The worse is over, BUT, he will have to stay on medication to get him through for the forseeable future.

 

As for marriage, his 7th house cusp Rulership is in Gemini, therefore, divided loyalties, or a division of his loyalty to one person, I would think, or a divorce is possible.

 

With his NN in the 2nd, puts his SN in the 8th, conjunct Mars.....best to stay on medication so he is not a danger to himself because these are two malefics now, (Saturn over Mars & the natal SN)
