Insecure Bride

So I’m terrified of how my wedding pictures are going to come out. I get married in August and have not found a dress yet. I’ve lost about 13 lbs in the past month which is encouraging but I keep slipping back into going to food when I’m stressed/emotional. My fiancé makes me feel like the most beautiful woman in the world❤️ But when I see myself in photos I don’t feel that way. Have any of you dealt with this? How did you deal with it on prepping for and on your wedding day?
