How to ask my doctor?

Eden

I'm only 5'4 and I'm 255 lbs. I want to see my dr and talk to her about options - specifically a weight loss medication to kick-start my weight loss. I've been eating right and exercising, plus I take Metformin and Levothyroxin. But I haven't lost anything still even though it's been months. What's the best way to bring it up to my doctor? I'm worried that my only being 20 might make her not prescribe?
