I wouldn't say move to another country ,
I agree it could be avoiding .
But if you live with your family
maybe staying with someone who is close by while working in therapy and
working on things with the family .
being in a different environment and being able to work on things
is proven to work better then being in the same environment that you are trying to work on .
Not to far away though . If i was in your shoes i would bring that suggestion up .
Maybe a friend or family friend , relative . ?
it is not healthy to be in a place where there are a lot of unresolved "secrets , "
or unknown things that cause tension .
I would look in to that and then go from there,
baby steps (:
good luck !
