Just looking for positives

I'm fairly new to this forum. I've tried other calorie counting sites but i love how this one counts the calories in my home made recipes. I don't have to input every item over and over again. It saves it. Awesome. Anyway, I'm not trying to lose alot of weight, only about 10 to 15lbs. I'm not overweight and have a healthy BMI luckily, but I just want to stop jiggling like jello in a swimsuit. It's been a little tough to find support to lose weight. Most everyone thinks that if your not labeled obese you don't have to worry about losing weight or need to exercise and eat right. So i get teased when i go for lower calorie options and sometimes even get told I might have a disorder. I still eat pie, cookies, burgers, and junk, but just b/c i limit myself on it or decide to control myself and take smaller portions doesn't mean i have a problem. (that was a vent). But anyway, i'm getting married in September and we're having a honeymoon in the mountains where we'll have lots of outdoor adventures. I want to look great and feel more confident on my honeymoon and make sure I have the energy for so many outdoor adventures. I just want to feel better about my weight. And even if i don't lose the 10lbs, as long as i can feel the difference in my endurance and muscle strength and jiggle a little less, i'll be happy. I used to be able to run 2 miles in 16min (a personal best) and was stronger than i looked. I've let myself go recently and i want to get back to how fit i was, if not better than what i was. So, wish me luck. And thx for reading
