Before: BMI 38
After: BMI 22
I've maintained for a few years now, and just found a new addiction for running purely thanks to a thread on here I started a few months ago (I was encouraged to try Parkrun and it's changing my life!).
Take things one day at a time, OP. Small goals. Small, permanent changes. Think health and fitness, not calories and slimness. Find new healthy, whole foods you love, try exercises until you find something you genuinely enjoy.
It does take time, but each day counts, each good decision matters, celebrate the good days and forgive yourself the not-so-good days.
You can do it, you really, really can. Deep down, I honestly never thought I'd actually lose my weight, it was such a part of me and my personality. I'd been obese all my life after several traumas.
Every day, I'm still surprised! If I can do it, so can you. Do it for you.
