Serious culture shock doesn't happen fast, it happens slowly. Often the person experiencing it doesn't understand what is happening - even for years. As an Irish-Israeli-Yemeni-UK-educated-Jewish-Catholic I am fairly much a citizen of the world...but Nationality and Home are radically different things. Years of digital nomadism sounds attractive on one level but will likely leave the OP with a profound feeling of something dark which they may never be able to name...
