I just want to congratulate you, even though i know you feel like your going insane you're clearly being really strong, i know you're stronger than what i think i would be.
Plus anyone would be going mad in your situation, its a really horrible thing to happen to someone, no one can really take that in their stride easily, so you're doing really well.
I know i would let anger consume me and then give up!
hope things sort themselves out, let us know how it goes?
