That sounds horrible. I wouldn't wish anyone to be alone.
My family has this sort of...curse with it. Basically, I look like a woman who was born 500 years ago, who looks like another woman who was involved in a spell 500 years before that which was performed by a witch on her son. So in another 500-something years, there will probably be another doppelganger being hunted for her blood. It scares me thinking about that possibility. I've already been through so much pain because of it.
