subtle robbery

i think it's scary how dementia robs you of yourself, transforms you into a monster - person from hell. when my dad came over and told me.. my first reaction was like 'cool' cos all the drama seems so unreal and it'd be cool to have been there.

but after some thought and reflection, i guess i would have been so scared tt i wont know what to do. how could she deteriorate to that state? to become some person i don't even know.. the grandma i know wont do that.. wont go all the way to that extent..
why? i mean how could she even resort to that?
it's shocking and frightening and unimaginable.
what's robbery? robbery by your own family? or you being robbed of you own personality but a disease that slowly eats into your mind. your brain. slowly takes away all memory..

why must it be this way? it's almost as bad as being a schizo.. it's terribly traumatizing to see someone you love transform into this state. a state which i thought would only happen in shows, some random case but never in a million years would i ever think that it would occur to my own loved one.
i'm scared. i dont wanna lose her.
