How do i stay motivated with going on a diet?

Whenever I feel bad, I really want to go on a diet. And I do for about a day, I do a good job, but the next day I feel like I should stay with my current weight. But then I feel really bad again.

I'm 5'1.5, and 116 pounds. I know it's not bad, but I...

gained 11 pounds in just a few weeks, so I feel really bad about my weight right now. Any ways to keep me on my diet?

get a weight loss buddy, its soo much easier when you have someone else to motivate you

Your really not over weight, but envision what you want to be, what clothes you want to wear, for instance. how you want ot feel, about how you look, or how you want to go clothes shopping, and re motivate from this point, it's all about smaller portions of healthy foods, like lean meats, fruits and veggies, exercise, and correct choices, when it comes to snacks, no soda, cookies, cakes, chips, you have to read nutritional labels and stick to one portion sizes and exercise 4-5 times a week, to achieve your goal.
