Thanks to all for your replies. She is finally going to her therapist. She has been seeing a psychiatrist and he has recommended her to this therapist and she finally made an appointment.
I do have a question. I can see also sense when my wife's mood has changed for the worse. What do I do? What do I say? When I try to talk to her you can tell she does not want to talk. Do I give her space?
Lastly, she loves our kids but our kids think we fight a lot. We argue especially up to her diagnosis. The part that really affects me is that she has a difficult time expressing her feelings to me. She only tells me she loves me when I say it to her. She kisses me only when I kiss her. She has a hard time smiling at me. I ask her if I am her stressor and if I make her happy she says "YES". When this happens it begins to snowball in my mind and then my mind wanders if it really is because of me. Is this normal? What do I think? ANy help would be greatly appreciated.
