I saw a therapist for 8 years and this pattern didn't go away. We worked on finding better hypotheses if I didn't get responses (from him or others). So instead of thinking 'he doesn't care' - I could think 'he hasn't managed to check email OR his email isn't working OR he has had emergencies to deal with..

It helped a little but not a LOT - and I'm still sensitive to people not responding. A therapist with a different (more depth psychology) approach pointed out that the fact that I wasn't responded to much (emotionally) as a child might be at the root of it. A baby knows it exists because it is reflected in mother's eyes - but what if the mother (because of her own pathology) cannot actually SEE the infant as its own little person? Not sure if being aware of this will help though :/
