Sister,
I've wanted to write this to you for months, but couldn't manage to get the words or message across just right. After thinking about how much this affects you on a daily basis, I've decided to just write this and tell you a few things in this letter. I will always be there for you as your older sister. Your anxiety doesn't make you any different. You never have to worry about me leaving your side.
From the time you were just a baby the separation anxiety you encountered was tremendous. You would run out of the doors from pre-k, scream for mommy as if you'd never see her again and cry until you couldn't breathe. As your much older sister, it was extremely hard to watch you react in such a way.
To this very day, you still suffer from this type of anxiety and even though you may deny it in order to make yourself seem stronger, I see it. I see the way you react to certain situations and I notice the way you tend to isolate yourself. When you tell me that it acts up and keeps you up at night is when I start to worry about you and my older sister instincts start to kick in. I worry for you and just hope that one day you can kill the anxiety that's lived in you basically your entire life.
No matter how many times you feel that your anxiety is eating you alive, or you feel like it'll never go away, I will never leave your side. I will walk with you, talk with you, even cry with you. I need you to know that I will be with you, by your side with you and I will conquer with you.
This might seem a little silly or general to some, but for the majority of people who know or love someone with separation anxiety, it can be painful and hard to watch. Sister, I am not leaving you. Many people will never understand our close-nit relationship because they simply don't understand you.
I love you unconditionally forever and always.
Love,
Your sister.
