Megan Foster · 4 years ago★★★★★
The journey of the 100lbs I have lost over the last 15 months has been a journey of self discovery and mindfulness. My before photo I was 275lbs, 2 months post divorce of a highly abusive marriage. My weight was a physical manifestation of the pain I was enduring in my life.
