I apologize for everything that I have done towards you...
Dear Me,
I am writing this with one simple purpose: To offer you forgiveness.
For all the times you believed you weren't good enough, smart enough, strong enough - I forgive you.
For all the harsh words you said to yourself, calling yourself names you would never call a friend - I forgive you.
For all the times you ignored your needs, for pushing yourself too far, or for not pushing yourself at all - I forgive you.
For all the versions of you that you are embarrassed by, that you wish you could erase and forget - I forgive them too. They were doing their best with what they had at the time.
You were simply learning. You were surviving under all that stress. You were trying to go through storms when you didn't have a map. Your mistakes do not the define the "you" now; they were lessons, though difficult. You are allowed to be happy with who you were, for they had built you to who you are now.
From this moment on, I choose to take care of you kindly. I choose to speak to you with love. I choose to not see you for your mistakes, but for the fact you stood back up.
You are forgiven. You are human. You are worthy to be loved; not only by yourself, but others too.
With all my love, You.
