Help!

Im injured and I can't get up!

It's no secret to my friends and family and most of my followers that I am injured with a messed up Achilles tendon issue.. I have been referred to an orthopedic surgeon to look over the injury and make a final verdict for a plan of action. It's good and bad. I have mixed emotions about it. I know I am going to be severely delayed in my plans, but I know if I don't get it taken care of, my goals could not happen - period.
At my last appointment, my doctor shared with me that it very well could have been my weight that caused the injury. I know I am probably sensitive to this or just frustrated cause I feel like I am capable of doing more than my body will let me. I am too fat to workout hard, the way I like to workout. I am too fat for kickboxing, for running (even the treadmills shake when I go over 5.0) and its like the world and now my body is saying, you are too fat to GET SKINNY!
I just feel like. WHAT. THE. HELL!?
I sulked for a few days and my foot hurt like hell. I tried to be more busy here and my foot hurt even more. Finally, my husband, and voice of reason, told me that I just had to take it easy. And I just started to cry. I brought up surgery because it's becoming clear to me that I can't do this on my own. I always thought I could, but apparently, I can't. I am STILL so frustrated I could cry. I begged him to let me look into a bi-lateral sleeve or a gastric bypass. And then I cried myself to sleep when he said no because he knows I can do it.
Friends. I am in a not so good fitness place. I KNOW I can do it, but in the most literal sense, my body won't let me. My husband is trying to be encouraging and uplifting and yet I want to scream at him because he just doesn't understand the stress and frustrations I feel over this kind of stuff. My biggest fear is to be 260 lbs again and without being able to workout, I just can't get it out of my mind that its going to happen.
Has anyone else been here? I feel like so much of the fitness community has only been mildly over weight and I am still, despite losing 50+ pounds, am still consider morbidly obese.
I am trying to take it back to the basics. I am trying to just take it one day at a time, one meal at a time, one small light workout at a time, one small goal at a time and I am just PRAYING that they add up - you too?
