Mummy, have you talked to any doctors? Could it be some kind of post partem depression?
As for GAD 24/7, I can speak to that as I suffered through it for 6 hellacious months recently. The GAD has been in remission (or I've recovered) for the past 2 months. Klonopin, ACT therapy and buddhist chanting helped me break through. And yes, when I had GAD I did lose feeling or connection with loved ones. It was a bit like social anxiety. But when I'd be with them, it's like l could only feel 40% of the intimacy I used to feel. Now that I'm recovered, all the feelings have returned.
