I think that the rhythm and rhyming throughout is good. I would change just a few things. For example, there should be a semicolon after 'meat' in the first stanza.
The second line in the third stanza should end with a full-stop. It's not grammatically correct to use a comma here as the next line talks about something completely different.
Finally, I have one more piece of advice. You don't have to use a full-stop or a comma at the end of every line. It was traditional to do that in the old days, but modern poetry shows that using a comma at the end of every line can be off-putting. It just disturbs the flow and it is even grammatically incorrect at times. For example
For I can't change the way I am,
And I'm not going to pretend.
there shouldn't be a comma after 'am'. When you use 'and' in a sentence you don't have to separate it with a comma, unless it's a list. For similar reasons you also don't have to capitalise every first word of every line.
I hope this helps. Overall, this was an enjoyable read.
Nathan.
