Kidding Myself

After I gave birth to daughter in December 2011, I was 78kg, my highest weight, I was telling myself and actually thinking that I wasn't that big. Then I moved to China and started eating healthier and walking more and in a couple months I got to 70kg, I finally went under 70kg in February this year. Since then I have been thinking I am eating less and excersizing more so the fat is coming off, but very slowly, I now weigh 64kg. But I have realised that in almost 6 months I have only lost around 8lbs. I still hate what I look like in everything, I thought I had lost so much weight but then I see other people who started the same as me and they are at 52 - 55kg now and I think wow, all that its just one burger, its just one coke its just one this or that has not helped me atall. The real reason for me not losing the weight is because i havent been tracking properly, or excdersizing, every monday is the monday i will start something and never continue. I feel so down right now. I have bought a treadmill, and I want to so badly stick to my calories. I know God will help me, and I thank God that I have realised it isnt me having a slow matabolism or anything, its basically me not tracking those hidden bites and not excersizing. My next goal is to lose 4kg, to get to 60kg, and then from there I will make another goal. I also love lifting, but never stick to it, and i cant go to the gym. i have the extension bands which attaches to the door, and i have 2 8lb weights. also cant buy anymore weights. How long will it take to lose 4kg, and do you have any excersize plan in mind? I will really appreciate your help. I am 23 years old. happily married, but surrounded by tiny beautiful chinese girls who have commented on my weight many many many timessssssss. I dress like a granny because i buy all the wrong clothes trying to 'hide' places, i just want to be freeeeeeeeeee. I know this is all my own doing, but by Gods grace everyone can turn around.
