How to get over the shame

My last A1C was over 10, and my next appointment is tomorrow morning. During quarantine I've been lazy, depressed. I haven't been exercising or eating right. I have a feeling my new A1C will only be marginally lower if not higher. The thing is, I am dreading talking to my doctor. I feel so ashamed, and I feel like she will be disappointed in me. It's enough guilt to not want to go at all. How do you guys cope with that feeling?
