if youre writing well then you should be using commas most of the sentences i write are two independent clauses joined together its called a compound sentence they give your writing more meaning and better flow but its easy to do it wrong   if you dont write with commas then your intended meaning can be harder for the reader to interpret it can be hard to know which sentences are related if you dont connect them with commas and a coordinating conjunction and or but yet so etc   commas are good thank you for using them the grammar that i hate is when people write using ellipsis instead of using commas ellipsis are the 3 periods in a row used when youre omitting words from a quote when you quote you can remove words from the original quote with 3 periods in a row   i like turtles and sheep so i went to the store they didnt have any turtles or sheep they should have both did i say i liked stuff   when i think of bad adhd writing i think of ellipsis not commas on the other hand your writing is very easy to read good job
