rb, your errors are actually quite interesting!
a few notes that might help you think about ways to improve --
a) your errors often involve things that MS Word can't help with, such as using a different word that sounds the same (called a "homonym").
Example: born and bread.
"bread" is something you eat. "bred" is the past tense of "to breed". MS Word is not smart enough to help with this, since both are valid words. So maybe you can take some time to learn homonyms in English.
This self-teaching tutorial might help you: http://a4esl.org/q/h/homonyms.html
b) You give the impression you learned most of your English from listening, rather than reading. This means you won't have as much info on how to write what you hear as someone who reads a lot. All I can suggest here is to read more of whatever you like best, emphasizing published works which are professionally edited, and try to note how spelling and punctuation are used.
c) get a sense of humor about this -- nobody's perfect at it, but it will be fun to improve. Check out this poem that passes any spell check perfectly, but has nearly every word wrong:

And good for you for wanting to improve! Corraggio!
P.S. "Oklahoma" is spelled like this.![]()
