Hi, Kaitie,
Believe me, not EVERYONE on this forum looses weight every week. I loose only 1 lb per month(if that). There are a lot of people for whom it takes awhile to loose. And that's ok. You will need to accept that it is a long process. I know it can be very frustrating, but the most important thing is to stick to it! Counting calories helped me a lot. If you stay around 1500 with all the exercise you do, things will go down.
Way to go on exercising at 10! It is better late then never. It just shows your determination, so give yourself a pat on the back.
I just have to say one thing - taking your time to loose is ok, because in the long process you condition your body to exercise and to eat right and you form new habits. After you loose all the weight, it will be easier for you to keep it off, because you will continue practicing those good habits. For people who loose weight fast it may be a bit harder to stick to the changes they made in their lives because they have not done it long enough.
So keep your chin up, and keep going!
