He is 20. His 2XL t-shirts that used to swamp him are now too tight. He gets breathless walking even short distances.
I feel like I'm watching him deteriorate in front of my eyes but there's nothing I can do. His addiction to junk food is too strong.
I keep thinking back to him as a baby, a toddler, a young child and it's breaking my heart. He was so happy, so full of life and energy - and now his life is so small and he's so sad and he just keeps getting bigger and bigger.
I can't bear it. I had him quite young and am facing the very real prospect of outliving him if something doesn't change. All I want is for him to be OK.
