Newbie Looking For Support

I'm really want to change my life. I've been overweight for a long time. I'm not really a junk food eater. I have just overtime eaten fast foods and heavy carbs. After the other day, I refuse to live life like this anymore. There is so much that I want to do but my weight is stopping me from being all that I can be. I'm not trying to be an athlete but I would like to one day maybe run a marathon, go hiking, do physical activities that I have seen others enjoy. I want my outside to match my inside and live the best life possible. Learning to eat healthy is a goal and what a sobering experience to input the foods and see how much what I eat has really been hurting me. It's hard because I really don't have anyone to encourage, support or understand because the people around me are thin. My current goal is to lose 130lb. I hope there are others out there who have struggled like me who can relate.
