New and ready for this journey!

Im new and Im not looking for a goal weight more along a goal size. Im currently a size 18/20 and wanting to get down to maybe a size 8 or 10. I mainly based my weight loss goal to be 150lbs, so I currently have a lil over 100lbs to go. Ive struggled with my weight for the majority of my life. Ive never been the thin girl. I just want to be healthy and live my life to the fullest. I just need the extra push when i feel like giving up. Looking for support, advice, reciepes and friends.
