Hi Tina!
I think most of us have felt at some point or another that 100 pounds or more to lose seemed impossible.
That is why I think it is better to focus on small goals instead of the big picture. Don't think about losing 100 pounds, think about losing 5 or 10 instead. Focus on eating healthy and exercising. Celebrate every little achievement you make. Think about what you can do today, not tomorrow.
I also think some sort of denial is normal. I too was in denial about the last 60-70 pounds that I gained. I still saw myself as weighing 180 instead of almost 250. I never considered myself as being obese, I thought I was just chubby. And then I saw the photos of myself at Christmas time and I was like YIKES! I never wanted to see another photo of myself like that again.
That is why I am here and I know I can do it if I truly try. Small steps. Hopefully next Christmas I will be happier with the photos I see!
I am happy to see you here as well. This is a great place...good luck on your new healthier life
