I've done this before (but it's not deja vu)

Weight has been a struggle my whole life. Yo yo diets, disordered thoughts and eating, fad after fad after failure. In my "adult" life I've lost to a low of 135 (what i weighed as an overweight 12 year old) and gained to a high of 210. Although at this high i wasn't happy with my physical form at all, I was the happiest I'd been in years so I stopped focusing on my weight as it crept over 200.

But this summer something changed. After a few miles of hiking (something I love doing in warm but not hot weather) a new pain showed up. Over the next few weeks a nagging knee pain became a new part of my life. Some weeks it's a quiet ache. Some days it's a stinging pain that won't allow me to bare weight.
I may be fat, but I've always been physical. This new issue has been making work a challenge (my job isn't sedentary) and taking away from my ability to enjoy certain activities, namely hiking as I'm nervous of being unable to put weight on a leg suddenly miles into a trail.
My whole family is heavy with bad knees. Both my 30ish and my 14 year old brother have needed knee surgeries.
I know taking excess weight off my knee will help and it should help my bad back as well.
So happy with everything but constant pain I've come back to make weight loss not a battle, but a journey. I think this will be one of the biggest challenges in my life because I've never been able to have a healthy relationship with food or weight before.
