I would suggest to you that you continue on the same road as before...attentive, listening, helping etc., so you can at least prevent a possible "trip" or outing on her part. That way, she would think about you.
Yes, it's time to seek professional help b/c everyone here means well and is truly concerned, but, this goes pretty deep and in my opinion, a professional will be able to talk to you one-on-one and really plan a counter-attack that would be more effective.
How is her demeanor lately? The same, or more quiet?
Hey, how cold is it there? How cold would it be in Germany now?
