She followed up with a second post of a more recent picture and a note about her future as an adult.

\"Being 18 and embarking upon my adult years, I can't predict what life will have in store for me. All I know is that I will try my very best to make a difference in this world with each moment that I'm given,\" she wrote.

....leading on from my last post, I have so much happiness in my heart for the journey to come. Being 18 and embarking upon my adult years, I can't predict what life will have in store for me. All I know is that I will try my very best to make a difference in this world with each moment that I'm given. Life is constantly evolving and I'm determined to find the light and love around every corner and share this with everyone who is a part of my story. Thank you so much to every single soul who took the time to read these last two posts, it means so much. I can't wait to see what is yet to come.

Just a few days earlier, Irwin posted a similar throwback photo in honor of her mother's birthday.

Happy Birthday to the strongest and most beautiful woman I know. Thank you for being my mother. You inspire me every day. I love you.
