I Fat Shamed My Daughter!

My 27 year old daughter is obese. Recently, a nutritionist told her she may have insulin resistance. I looked at it as a wake up call for her to stop eating sugar, and became a raging interventionist, thinking I was doing the right thing by her, and she took it as I was fat shaming her. She also said the reason she has food and weight issues is because of me and my obsession with food & weight. I’ve tried so hard not to project my issues on her but I’ve obviously failed! How can I make this right? I love her and I’m concerned for her health and now she’s not speaking to me! I apologized but the damage is done!
