I think she will need to come back to the UK eventually. I cannot see such a socially insensitive and cloth eared women like her surviving for 10 minutes in another country where she would be expected to to take responsibility for her actions and accept that actions have consequences.
I think underlying everything she has done has been an implicit belief, never consciously expressed, that, as she was a British citizen, if everything went pear-shaped, someone would rescue her from the mess and take her home.
It has never once occurred to her in all she underwent - and I have no doubt that the experience has been horrendous, that the moment she got away from ISIS, she wouldn't be whisked home courtesy of the Foreign Office and returned to the bosom of her family and the safety of the UK.
You can see that attitude in the early interviews where she still espoused ISIS and defended its actions, and yet expected to be rescued and brought home. You can see reality beginning to dawn it in the way she has been gradually less enthusiastic about ISIS and upset because 'she thought people would be sorry for her' and you can see reality crashing in on her in those photographs of her reading the formal letter from Sajid Javid withdrawing her British citizenship.
Suddenly she is realising that actions have consequences and the person who makes the actions must live with the consequences.
I think a couple of months in a refugee camp as a stateless citizen, will do her a power of good. She will have plenty of time to think and when her citizenship is finally accepted, with a bit of luck she will return a sadder and wiser woman, who might even realise that you need to think through the consequences of your actions and accept that you will reap what you sow.
