Falling Inside the Black Lyrics Meaning

I personally think it's about a person going through a dark time in their life from a now neglecting partner. They're going through a rough patch and falling inside a dark mental state from not getting the love or support they used to get.

Their lovers dry
Their lovers cold
Their lover left them alone

The longer this keeps going on, the deeper they fall into the black abyss. They want the old lover back. They want the (What seemed to be like) caring, kind, person back. But their lover can't hear their cries for help and they stay neglecting them.
