I'm sorry this happened. Talk about when it rains, it pours. Just know, we all have obstacles we face through our journey, so don't feel alone in this. Keep on pushing and things will eventually look up (keep reminding yourself this and you will see) Look on youtube or search online for exercises you can do that wont hurt your knees and stuff. Also, just watch what you eat, pretend you have a fill and keep eating like you have all the restriction in the world. I can't afford a fill right now and would really want to go see the OCC for a checkup but I can't afford it right now, so I trick myself in thinking I have restriction and only put on my plate what I think is appropriate for when I do have restriction. Don't let your financial situation determine your weight loss, I hope and wish you lots of success and smiles and rainbows and unicorns... big hug!!
