Crystal tears of sky,

I like the image of rain filled sky. Also the metaphor of big emotion: a sky full of emotion.
Cluster of desolate truth.

In this sky a loneliness brought on by a revelation. This line is nicely weighted.
Lave drought surrounding the earth;

Is the word 'Lave' a typo for 'Love'? If so the idea of this desolate raw emotion is starving the emotion of love, preventing it from being released.
Drench me by your catharsis.

A lovely last line. A plea to the heavens to purge this pity with cleansing rain.
