My teeth!

Omg my teeth are so bad right now! I was severely depressed and let myself all the way go. Now that im coming out of it im realizing the damage thats been done. I gained 90 pounds and my teeth are trash now from not brushing. Im sooo embarrassed to go to the dentist! My anxiety is getting the best of me and I feel like they'll judge me. Im too young for my mouth to be in the condition that it is. What do I even say when I call?
