Could someone please proofread my letter because it’s for my business english class for college? Could someone tell me if I have some errors?

My name is Kayla Green and I’m 26 years old. I’m currently a student at Lonestar college Cy-Fair in Houston Texas. My interest and concern is the new health care reform law, because of my preexisting condition. My diagnosis is Vonwilliebrands disease, which is a genetic bleeding disorder. I’m currently enrolled in the Texas high risk pool insurance because I was denied from applying other health insurances.

My strongest passion about the lifetime maximum is that it gives people a lifetime coverage with no limited boundaries. Iam for this lifetime benefit because health insurance can’t cancel your coverage when you reached the maximum. When medical claims exceed their lifetime limit, this reform law will benefit people with serious medical conditions that require expensive treatment.

Another strong ruling of the reform includes various preventive health care services will be free. Many people would be able to take advantage of the free services.

Please vote for additional changes or ammendments for the health care reform bill.
I would like to thank you for your time and effort for passing this bill that was needed for many years. The most important thing is keeping people healthy.

The professional letter has to be about what I’m passion about, please help!
