I get accused of putting too many in, but where I put them, is exactly where if the sentence was spoken, the pauses would be. And that's how it should be.
So, in, other, words, if, I, talk, like, a, west, Texan, I, should, write, something, like, this?
And what if I talk like a New York Jew should I just omit the punctuation altogether since it all gets swallowed up anyway as I cram in all the words I can possibly speak?

If the character talks that way, then yes. Be true to your character. Or better yet, don't have a character talk that way.

I'm in comma purgatory. Been accused by readers of having too many freaking commas. I try to put them in where they should be in speech, but it ends up being too much. Editor agrees with readers. So I don't know what the right answer is, but I'm trying to be more picky about commas.
I've been accused of having too many commas, not enough commas, and commas in the wrong place, all for the same book.
As I say in my author notes, I comma as I read aloud. If I pause while reading, it gets a comma. And how I read it, is how I expect it to be read.
Texans may have an issue with not enough. Noted. NYJ's may have an issue with too many. Noted.
But my characters are mainly Australian, so that's how they're written. And yes, I do talk this way, for real.
