Can anyone make any sense of this?

Here’s a poem I decided to study for my imminent English paper on Monday, but I don’t actually know why, seeing as how I have little to no idea how to interpret this. Perhaps if any of you have ideas, leave a line or two in the comments. Otherwise, just enjoy/scratch your head like me.

The little people in the radio are picking on me
again. It is sunny, but they are going to make it
rain. I do not like their voices, they have voices
like cold tea with skin on. I go O O O.

The flowers are plastic. There is all dust
on the petals. I go Ugh. Real flowers die,
but at least they are a comfort to us all.
I know them by name, listed. Rose. Tulip. Lily.

I live inside someone else’s head. He hears me
with his stethoscope, so it is no use
sneaking home at five o’ clock to his nice house
because I am in his ear going Breathe Breathe.

I might take my eye out and swallow it
to bring some attention to myself. Winston did.
His name was in the paper. For the time being
I make noises to annoy them and then I go
B A S T A R D S.
