Have you looked into PTSD or Borderline Personality Disorder? You mention bipolar, but while bipolar episodes can certainly be triggered by stress, PTSD and BPD are more reactive to outside events, especially with a history of a "personal painful story". A lot of people throw the idea of bipolar around when they are moody, but bipolar is so much more than moody.

None of us are doctors, so it would be best to talk to one - but I think it's absolutely reasonable that the stress of the move could be reactivating your anxiety disorder.
