Do you think i am fat?

im 15 years old and 5'2'' and i weigh 135.5. i do tumbling (flips, similair to gymnastics) throughout the year and cheering fall/winter season. i lose weight pretty quick but it takes a lot to get me motivated and NOT give up when im not doing cheerleading related things such as push ups and running especially. do you think i am overweight? i personally want to get to 130 lbs. but like i said it takes a lot to get me motivated. do you have any tips on that? or dieting? please give me some advice and be nice:) thank you so much!
