\"It's interesting that I'm still smiling and still trying to be active -- this was taken at a charity tennis tournament event ... despite being in so much pain,\" Wilson continued. \"I look back now at that girl and am so proud of what she's become and achieved.\"

As for why she wanted to be honest about such a vulnerable moment in her life, the \"Bridesmaids\" actress expressed she \"wanted to send out some encouragement to everyone out there struggling with weight or body issues or emotional eating.\"

\"I feel you,\" she wrote, addressing those struggling. \"I know what it's like. But it's never too late to start improving yourself and trying to be the best version of YOU possible.\"

\"It's not a race and it's not a competition -- it's about respecting yourself and doing what's best for YOU,\" Wilson stressed. \"So if you're out there and reading this today, I just wanted to say: keep smiling and keep trying to be active!\"
