You will. I'm 44 - and the one thing I wish is that I'd been less insecure when I was younger - and had less to be insecure about! Now, I am. Acceptance has set in, and I get attention when I choose to. Truthfully, it's a relief to not spend my every day worrying about whether or not I'm attractive that day, whether or not that cute man at the grocery store noticed me....I'm very comfortable in my skin.
The wrinkles and sags and stretch marks...do I love them? Nah. But, they are signs of a life well-lived. The stretch marks are from pregnancy - I had 4 beautiful children. The saggy breasts are from breast-feeding, which I don't regret for a moment. The rest of the sag is gravity, which plays no favorites. And the wrinkles. Wrinkles from laughing and smiling, wrinkles from frowns and tears, wrinkles as a result of many wonderful days in the sun...they are truly my life, written on my face. I wouldn't remove a single one if it meant the loss of the events and feelings that have made me the person I am today - someone I like.
