Alisha, this is great. Great communication skills will help you SO MUCH in your career. Nothing kills the mood more than an obvious typo or wrong apostrophe in an otherwise great presentation (it's vs. its!!). Whatever you end up doing, being able to deliver well-written information will give you a lot of credibility.
If you are still in college, try to take one or two humanities classes where you can work on your writing (not too many, don't get distracted). Have your essays proof-read by somebody. I agree Word can help, but there's a limit to what it can do with style and register. Also, read a lot beyond technical stuff: technical writing is often very limited in language and structure. Get inspired!
