Along with our home we often lose much more: familiar people, language, social status, professional confidence, favourite places, the ease of everyday life, the feeling of "I know how everything works here".
Sometimes a person seems to carry on with their life, yet inside feels as if their real life stayed somewhere else.
It can be especially hard when the new country is objectively safe and comfortable but hasn't yet become home emotionally.
Then loneliness, irritability and a sense of not belonging can appear, or guilt that "I'm fine here", or the opposite: constantly comparing the new life with the old one.
Emigration often changes your identity. Before, it was clear who I was, where my people were, what my professional role was and where I stood in society. Then much of that has to be pieced together again.
That's why adapting is not just learning the language, finding a job and sorting out documents. It's also gradually building new footing without giving up the earlier part of yourself.
In therapy there is room for grief over what was lost, for anger, confusion, nostalgia and fear of the future.
You don't have to choose between "my past" and "my new life".
Sometimes the task is to gradually allow yourself to be someone who can have more than one home.
