As someone who scrapbooks. please suck it up and be in the picture.
I noticed myself, that although I take pictures, I was rarely in them. I don't like my picture taken either, but I now make sure that I am in some photos. On Mother's day, I love to have my pic taken every year with my kiddos. Do I always look the greatest? No. But, I treasure those photos and I am hoping that someday in the future, they will also treasure those photos when I am gone.
I wish we would have gotten a family photo taken before my father passed away. It was sudden, so could not foresee the future, but I would have loved a family photo with dad in it.
