How will he cope on release from prison - from Anonymous

Dear Prison Widow UK

My son is in prison and will be released very soon. He has already told me and his father that he doesn't know how he will cope when is released. We are worried because he has a very negative attitude at the moment and we have noticed a change in him when we have visited. 
It is as though he has lost his spark and whilst me and his father are excited to be having him home again, he is not showing the same enthusiasm. We understand that it will be a big change for him so I was wondering if any of your readers can offer some advice? Thank you in advance.
