Goooooooooo Giiiiiinnnnnaaaaaaaaaaaa! I completely know what you are going through but I gained A LOT more than 7 pounds! But ya know what? It came off (eventually) and I'm a lot healthier for it. I'm not going to lie though, it's by far the hardest thing I've ever done and will ever do in my lifetime.
Keep your chin up and know that it gets easier but it takes a lot of patience. If you want to talk you know where to find me
