It still can get unhealthy lonely, especially when you lack the basic social framework of family, assuming you stay away from your family and relatives. This means a day of two when you haven't spoken to anyone. Staying alone is completely fine, but at least set up 10 minutes for social interaction. For some people it happens organically, that they don't have to allocate any time. For others, setting that time is necessary, even if it means calling your friends who stay far away from you.
