This is a pretty well-written short, but it seems the last two lines throw it off because they don't fit the style of the first two. Maybe you should try something of this sort...
throw me out lonely and cold
this whole charade is becoming old
you've left me alone to carry no meaning
you are the depth behind my screaming
I've shortened the last two, leaving out the parts that don't necessarily contribute heavily to the poem. Therefore, allowing the flow to continue smoothly while still showing emotion.
Also, I changed "all so" to "becoming" because it seems to flow better as well.
These are just suggestions and not harsh criticisms, because you have written a poem that has a lot of potential. And growing to that potential is what these comments are meant for.
