I used to have this problem. Actually still sort of have this problem. I wasn't always a big girl. I used to be a size S or once in a while M. But then I moved had some health issues where I stayed in bed most of the winter, here's its like almost 6 months of the year. Then BOOM, I balloned :cry:.
So I knew I got big when I had to wear a size L, and was making my way to XL. When I saw myself in the mirror I knew I was bigger then I used to be, I didn't look like me, but I thought well not too bad. Then a picture pops up and it's like OMG What the...who...omg it's ME

!!!
The bigger wake up call was when I went home to visit, and was with my family and I felt HUGE compared to everyone else, and in the pics I was HUGE! Actually what's sad is my family almost didn't recognize me at the airport, they had to do a double take

I was in denial and didn't take pics and didn't tell my family about the weight gain, until the week before I went to see them.
Over a month ago I went to a wedding, I thought I was looking so much better than earlier in the year since I started working out a little, and my clothes felt looser. But when a friend took a picture for me of me and my guy, I looked HUGE! I looked like a bee stung my whole body and face, so it was another reality check.
Now that I've lost a little weight, and see myself in the mirror and think wow I look so much better. But then when I see friends next to me by a window reflection or a mirror I still know I have a ways to go
