maybe I can help you because I feel like you may be very similar to how I was (and still am in some ways) I am also 25 and have been over weight for 7 years (slowly climbing every year)I struggle with depression and I also lack some kind of structure in my life.
My breaking point was mid october when my nosey old neighbor told me I was gaining weight. I was so depressed! I tried to formulate a plan but inside I felt a voice telling me that it wasn't going to work and I felt defeated before I even started but then something cool happened....I got angry. I was sick of being overweight soooo sick of it, so sick of not reaching my potential in my mid 20s because i was insecure over my weight. I was so happy in other areas of my life after struggling for years from depression and substance abuse and I finally was where I wanted to be and the only thing i couldn't get under control was my weight. So I decided to start small and see how I felt so I restricted my carbs for 2 weeks to see If i could get all those good benifits I was reading about. I didn't think I would do it for too long because i didnt believe in myself to begin with but i kept pushing and saying to myself that I can not turn back. slowly I started enjoying the little things about my weight loss and not getting impatient and saying "I WANT TO BE THIN NOW" I enjoyed the ride, my skin was glowing, I had more energy, I wasn't as hungry. My world didn't revolve around food anymore. I was doing it without even thinking. I honestly had no idea I would have lasted this long and I do give myself leeway and i'm not as strict as when i started and I will eat a sweet potato or a chocolate (probably on valentines day
). I still go out and have a drink with my friends. But start small and you will gain momentum. I've never lost 25 pounds ever in my life and I can't believe I was that same person that started with all that doubt. You can flip your switch I promise, if i can do it you can
