Help 7 lbs in 6 months only :((

Hey I really need help I've been trying so hard to lose weight but so far I've only lost 7 lbs in 6 months. I started in January and essentially lose 1 lb per week, then my weight loss hit a plateau. It doesn't help that my height is 4.89ft for someone who is an adult woman, so I find it almost impossible to lose weight! Arghh so frustrated any advice would be appreciated to help me lose weight faster!
