What is wrong with my brother?

[monkophile]

Granted, I live several states away so have not seen him; just going by what I've heard from my parents:

 

I was home for Christmas; saw him New Year's Eve and left back to my city on New Year's Day....all this started just a week or two after this. Just out of the clear blue as on New Year's Eve he seemed perfectly fine.

 

My brother has been married for about eight years; he will turn 30 next month and they have a three-year old daughter with another child on the way.

 

It may have started even before this but noticeably started with my brother messing around with another woman; thankfully the other woman is out of the picture.

 

He is moody, depressed, won't eat. He is seeing a psychologist, a psychiatrist and is now starting to take anti-depressants and anxiety medication.

 

Unfortunately he is not eating and so the doc told him he has to eat for the medication to work.

 

I am coming home for a week for Easter. My parents told him weeks ago that I was coming home and he seemed excited. Yesterday (a really bad day) my mom said "you know your sister is coming home for Easter, right?" He said "no, when's she going to be home?" He's never that forgetful.

 

I think what he needs is one of those cat scans that show the chemicals in the brain cause obviously something is not right with him.

 

I am extremely close to my brother and it pains me to hear all this happening; it's going to be even worse when I see him...IF I see him - he may not want to see me, which pains me even more.

 

Please, I am begging you, please tell me what you think is going on. I was thinking some sort of mid-life crisis, but he's only 30 and the more I hear about it, the less it sounds like that. He has never, ever had anything like this before. He doesn't smoke and rarely if ever drinks. He doesn't do drugs, either.

 

It's taking a toll on my family as his wife (who's midway through her pregnancy) has high blood pressure and high sugar and keeps losing weight (I fear for the baby!) and the three-year old is starting to cry, saying she misses her daddy.
