Hard Decisions

So I had a meeting with my lawyer this morning regarding my case. Needless to say it wasn't the best of meetings.  I am now at a crossroads as to how to proceed. I essentially have three options. The first one I don't want to do. I just don't know.  Piece of mind doesn't fix my foot. Nothing will fix my foot. Going into depression because of an injury is frustrating.  I'm young and pretty much I can't continue doing things that I love to do because of the pain I'm in almost daily sucks. I miss dancing. I miss Zumba. I miss being active cardio wise. Because of this injury I have gained about 60lbs. You wouldn't really notice it looking at me, but when you get asked all the time "when you're due" you know it is there. I want to lose this weight, but I dont know how without incorporating cardio. I already eat well, but that doesn't get rid of the fat.
It is hard to stay positive when your youth has been taken away from you. If the pain wasn't so bad, I would just work through it. But with that I worry that I could make it worse. Although with my foot already being slightly deformed,  how much worse could it get?
