I think of Elsa to be one of the more relatable Disney Princesses. Here's my take on her. Please forgive me if I'm wrong. This is just how I see her.
I see Elsa as the depressed princess. She has an amazing talent, but she suffers from something she hasn't learned to control. She fears how it will effect others so she tries to keep it inside. Don't let them in. Dont' let them see that inside you aren't the perfect girl they want you to be. The pain of the affliction trains you to conceal as you try not to feel the torture in your heart and mind. All you want to do is let it go. Give in to what is screaming through your veins day and night. Most I know try different routes with dealing with the storm inside. They numb themselves to it. They let it go by going wild. Trying every fix they can get their hands on to quiet things down a bit. More lock themselves away, like Elsa did. They slam the door on anyone, scared that they will hurt the ones they love. Even more give into the sadness and hurt. They literally drown, having given up on finding a way out.
Love is what is needed to cure the storm. True it doesn't happen right away. It takes work to realize the love around you. To see that you are safe to be you in your environment or to even find the place where you can learn to control the pain instead of fearing of hurting others. However, not many understand. The misunderstanding causes those who are effected to hide. They feel bad that no one gets what is going on or even worse think there is something wrong with themselves because no one else is this bad off. How can the world smile when you are trying to breathe? Love is needed. Just love them. Let them know they are loved. They are not alone. For the first time in forever they do not have to be alone.
