Whenever I was depressed, I let the sounds of the secret Forest and the feeling of raindrops and sadness wash over me. Then the relief that I could still see made me feel comfortable.
In some cases, letting sadness flow will make it less difficult for you. The world tells you to hold back your emotions and tries to frame you a certain way, but you can be yourself when you are in Sky kingdom. It's okay if I can't see well. I am still me, the child of light in the Sky kingdom, and a free-dancing butterfly. Sky, for letting me know this, I thank you very much.
