Ok, first off, I know I'm young so I relate to weight-loss/gain in a different way than older people, but I do feel like I have something to offer because, even at the young age I am, I've struggled with being overweight, body image, and weight loss.
I used to be overweight. I tried going on Weight Watchers (modified for my age, more calories and so forth and my "group leader" talked to me more about exercise) which helped me lose somewhere from 15-20lbs. I kept that off for a bit, but I then got off Weight Watchers and stopped going to WW and gained it all plus more. Then I tried going to Curves with my mom for a while(by the way, I later found out the CEO is a very, very 'pro-life' person with radical vies who is not someone I'd like to support). I liked it a lot, but with school it was hard to find the time so I never really got results from that. Then, later that year, I think I just started deciding enough was enough and I started eating more healthfully. A lot of the key to me was a healthy lunch. Instead of some fattening crap I'd eat a bit of chicken breast, some carrot sticks, some fruit, and sometimes and 100 calorie pack or something like that. Sometimes I'd have light yogurt too, which I really like. Also, when I felt like eating a snack when I wasn't hungry, even full, I'd just force myself to resist it.
Suprisingly, exercise (besides unstrenuous PE, haha) wasn't a big roll in my weight loss. (which ended up being about 35-40lbs). But I think it is very important, and I would recommend yoga and running or jogging. They balance each other out, and I've currently started doing them both.
So, my recommendations for doing stuff physically:
-Healthy lunch
-Healthy breakfast
-No unhealthy mid-morning snack (carrots, fruit, etc. are fine)
-Resist stuff that's just sitting around
-Eat plenty of fiber
-Low-fat is the way to go w/ stuff
-Do aerobic excercise 3-5 times a week
-Try to do some strengthening yoga or pilates at least twice a week
Psychologically:
-Always remember all the great things your body can do.

-You aren't unworthy of anything because of a few extra pounds
It's about finding a healthy lifestyle and gaining confidence that you're great!
Good luck, and we're always here to give you support!
