Karen ,
So much of her issues seen to be all in anticipatory anxiety rather than situational . It may be worth talking to the counsellor to see if she would do a session specifically on that sometime. It may be to do with separation as shes indicated but it could also just be habitual now.
For ages after I'd really finished with major anxiety and fear , I would have anticipatory anxiety symptoms of nausea and churning when travelling distances even though I wasn't really scared of anything at all.
