I'm Still Not Losing

I'm still struggling with my weight. I only lost 2 pounds since I start my diet. Yesterday I tried to wear two of my favorite jeans but they're still really tight for me. I'm starting to get really disappointed to myself because it's been two months since I've been trying of losing weight but I only lost 2 pounds. I'm still doing bad with my diet, I still eat a lot of junk foods and I'm too lazy to exercise. My goal is to lose at least 10 pounds at the end of this year but I don't think if it's gonna happen if I don't get serious with my diet. I will try my best to exercise tomorrow and not to eat junk foods.
