To the girl who masks her true personality because of social pressure and anxiety, you are not a burden and you are not alone.
Your emotions are valid and very much real. Your emotional pain of feeling unworthy and invalid will pass and you will thrive.
To the girl behind the mask who says "I'm fine," when asked if you're okay, one day you'll be able to say you're fine and mean it, but today you can't and that's okay.
Some day soon you'll be able to put the feelings of no-self-worth aside and say to yourself you're worth it. You're worth feeling content and happy with your life.
To the girl who is afraid of taking her masks off, remember the feeling of ease and comfort you had before the masks existed.
Your strength shines through your mask and everyone around you sees your value, even if you can't see it yourself. You were made for beautiful things... Things that will bring the feeling of fulfillment that you crave.
To the girl that carries the weight of the world behind that mask, some day you'll feel a lightness in your life that's so brilliant.
So hang on to hope and remember that this will pass and you will shine brighter than the brightest star in the sky. Some day you will be able to accept the person who hides behind the mask, and when that day comes you will no longer feel the burden of mental anxiety.
Stay strong and prosper on.
