Paroles de Rest among the silt

When it's dark and i'm alone i cry for peace but they won't go.
And this is killing me but i can never let you know
It's more than i can take, i sink - i drown - i cannot float
And they keep pushing me the rope constricts my fucking throat again...
You don't know what it's like if you did you'd never want me
To be there - and if i made you understand, you'd have
It an you'd be in this mess!!!
Dragged down to rest among the silt, i cannot breathe it's ???

(the rest of the lyrics are too hard for me to interpret)
