Wow Ice Lolly. For such a young girl you are having to go through a lot.
I havn't read your journal...sorry....but now I have read what you are going through, I will read it.
Much of your symtpoms sound consistent with depression and anxiety. However, the fact you cannot regulate your own body temperature, this sounds like it could be viral, or some other kind of infection.
I do not know your history, but it is possible that you may be suffering from an infection or another physical illness that is causing you all of these symtoms. You may have depression as well as a non-mental illness, or perhaps you have an illness causing you to de depressed.
It does sound like a good idea that you are getting all these tests done. Please do not be scared.
I think it is completly out of order that you have been banned from complaining at home. Considering what you are feeling like, it is no wonder that you have a need to expressed yourself. Keeping things bottled up is not mature at all. You are doing the right thing by getting this out in the open.
I hope you get answers soon.
Love Steve X
