For some Suicide is the ultimate self protection - Self destruct due to the horror/difficulty of life. Sounds daft dosent it!
Im a married man with two kids, 9 and 6. I have explained to my daughter (9) that Daddy gets a bit sad now and then but I have some medicine which im taking to help me out. I leave it at that. No point going into the depths of depression and all its co-morbiditys, kids dont understand and can get confused and take the blame on themselves.
My wife is understanding (her mother had been commited to hospital twice when my wife was young due to serious depression so she knows the score).
For me depression (pre meds), was hellish, I felt very down, all rational thoughts dissapeared and each day was a real struggle. Now (that im on meds Mirtazapine 45mg ) my depression is quite mild but I do have some oddities that run with it such as Intrusive thoughts (these are difficult to cope with), a "Weirded out" feeling, anxiety and sometimes a tarred/tainted outlook. But...I know I have depression, I know its not me really that is feeling like this. Im sick, Im ill, im taking medication just like anyone would for an illness of the body, it just happens to be my brain thats not working to great. I personally feel that your wife needs intense therapy/counselling as soon as possible. If she gets too bad and is seriously threatening her own life it may be the case that she needs to be looked after at hospital?? One thing I know for sure is that the stress of children is VERY difficult to cope with when im depressed. She may need space and time to sort it out on her own? But as for divorce, if the professional did say that, then its not professional at all. What about family therapy?
