I already have a lot of problems, your family's are not my business.

[A Brazilian and a monkey]

I was going to buy bread this morning and witnessed an argument between a young lady and her husband. At some point she said a few things.
I transcribed it into English and I would like to know if it is grammatically correct:

"I already have a lot of problems, your family's are not my business."

Thank you.

Yes, it is.

 

[A Brazilian and a monkey]

Yes, it is.

Thank you, Rover.

If I may, could you tell me if this construction sounds natural in spoken English?

You need a semi-colon after problems. At the moment, you have a comma splice.

Thank you, Rover.

If I may, Could you tell me if this construction sounds natural in spoken English?

Only if it's clear whose family she's talking about.
