Allen, Sounds to me like you don't have a supportive family, so guess what WE will be your new family! How's that???
Your family and tons of other people don't understand how the mind affects the body. Take the placebo effect for example...if a person thinks the sugar pill is a highly potent new drug it often works just as effectively as if it had been, in fact, a highly potent new drug! So if your mind is in pain the body responds according. And also, every cell in the body has a memory of its own, so every cell in your body "remembering" both the physical trauma you went through and the mental.
And also if you were to have a scan done on your brain to register heat, more portions of a brain effected with PTSD will show bright red, than you will find in a brain of a person who does not suffer from the..I hate to use the word disorder - so than you would find in nontraumatized person.
