First of all, bless you for taking him into your home! You saved his life!

It seems like Manchester hasnt shaken the trauma of what happened to him in the woods. I cant imagine what that poor boy had to deal with! I have no experience in the matter, but common sense tells me that he needs some help. I think the $ you spend now will be far less than what you will pay both financially and emotionally if you dont. He sounds like a PTSD victim, for which I do have experience in.

Good luck!
