reddeborah, I'm with you. I was not chubby as a child, I was a skinny little shrimp. For years as an adult my weight was stable at around 120. Then I started to gain, and it took decades (I'm 58) for me to get to my current weight (185). Inside, I still feel like I weigh 120! It's such a shock to see myself in a mirror, even though I've been like this for so long. "What happened?" I'm always saying.
Don't be afraid of "getting skinny" until it happens and you can experience what it's like. Let other people worry about their own reactions, including DH's, DB's, DW's, whatever!
