Ian,
Iv'e been off the grid for a while (stuck in an algebra class that seems to be consuming any all brain capacity that I have...lol)
but, I see that your home and you seemed pretty exicited about it, but your last post seems like there is some frustraion in your tone. Have you gotten anywhere with your psycologist??? I would think that when you left there, they would have set up some regular visits, to keep things in check for a while, until you get adjusted. I seems like they just kinda went ---'well, ok, here ya go, be free..' Maybe I'm wrong, I'm not there, so I really don't know all the details.
I'm so sorry that you still having problems sleeping, I'm sure that is probaly also adding to your body aches and general well being. When your tired, everything is worse. Try to pay attenetion to things that are different on the nights that you DO sleep, the events of the day.. Did you work out that day? Did you go out? Was it a calm day? Was it an emotional day??? Try to find out what different on those days, and maybe you can re-create it and hopefully it will have a positive outcome on your sleep. I can't promiss it'll work, but hey, when you're not sleeping well, anything is worth a shot :-)
