“They won’t tell me anything until my social worker and psychiatric nurse share my case history.”
Can you try to stay on top of that? Like as soon as the information becomes available, find out all you can?
It sounds like a good move to me. Have you ever seen Maslow’s Hierarchy of Needs? http://en.wikipedia.org/wiki/Maslow's_hierarchy_of_needs Things need to be ok in the basic areas of your life. It’s the foundation you use to build the rest of your life.
It sounds like you’ll be better provided for and will spend time with other people during your day. That sounds like an improvement over the current situation. If things aren’t working out for you, sometimes the best way forward is to make a big change.
I would definitely make sure your social worker, etc. answer all of your important questions before you go. You could also ask if they can put you in touch with someone who lives there already, so you can ask them what it’s like.
Good luck. :)
