I played college golf and professionally from 2000-2007. I feel qualified to answer this question.
The easiest way to lower your handicap is to improve your game from 100 yards and in. This takes a lot of practice. Think of how many strokes you waste just around the greens. How many putts do you miss inside of 5 feet? Just improving your putting alone can lower your handicap by a few strokes.
Find a local teaching professional that you feel comfortable with (there are many women teachers if you feel more comfortable with them). Set up lessons and then practice what you learn on your own between scheduled lessons. With hard work and accepting what they are trying to teach you, you will become successful and shoot lower scores.
Let me know if I can answer any other golf related questions.
