The sort of shit Jo had to go through really effects her entire life. This can be mitigated through counseling and perhaps medication but it is a long tough process that never really ends. I am living this through my grandson who is now in my care. It is tough... tougher not to know at first and then try to deal with it on the backside. Security will help a great deal... the more security you can give her the more serenity you shall receive (there is a lot of security in a simple hug, those are free and can be delivered often )
