Hello. These could be warning signs that need not be ignored. Are there others like family or friends that have also observed these changes? If so, it may help for them to express their feelings to him as well. Is there any substance abuse, alcohol or other? Is this having an effect on his work? Aa previously stated, you need to look out for the well being of yourself and your children, and being armed with the facts and support of others could be very important. Keep posting and take care, GM
I'm sorry your family is going through such rough times. Well, we all know that when someone starts talking about suicide that it should be taken seriously and reacted too immediate. Deep depression does not normally go away on it's own. and normally tends to worsen over time if left untreated.
If he will not take medication that will help him, will he go to therapy? Speak with a Minister, a friend? Does he trust anyone? Have you told him you are concerned about his safety? The well being of your family ? Honestly, I am sure you have already told him all of this...what happens if he doesn't get help? I don't know, but if he will not seek help you may have to speak with a professional...oh, and don't forget you and your childrens mental health going thru all of this....you must take care of yourself and definitely those kids.
