I understand how you feel about wanting to get to your goal right away. Your chart shows a lot of progress so you're doing really well.
I've learned after years of yo-yo dieting that slow weight loss is best. It's taken me about 4 months to lose 12 pounds! But when I look back at it, I achieved a better lifestyle. So it's the little achievements along the way that makes the ultimate goal so much more satisfying.
Keep up the good work, you're doing wonderfully.
