I'm coming back to ballet after 3 years break and I'm scared

I used to be a professional dancer till I had to quit for my health, but next Wednesday will be my first time back and I am soo excited. I am finally healthy enough to come back even just as a hobby. I am soo happy and excited but also so scared at the same time. My body isn't the ideal ballet dancer's body anymore and i have hard time accepting it and im scared others will judge me. I am also so scared I have forgotten it all. It is an intermediate level class but im scared I've lost my skill. But in the end I am so happy, i thought i would never dance again and I proved myself and everyone wrong.
