Have you considered maybe becoming an instructor at a fire fighting school or something like that? Maybe you could find a temporary job doing something like that while you wait to see how long things will last for then maybe you will see if you are ready to go back or maybe you'll try a different path?

I am just returning to school myself. I took one class this semester and it went well so I am going to try two come september. I am 29 months into my recovery and man I am much better than I was at 1 year! Still have a long way to go but I am getting really good at planning my life so I can be the most efficient and limit making my symptoms worse. I was doing search and rescue before my accident and miss it a lot. I am not sure if I will ever return to it but I have considered doing talks to kids so that I can still have some part of that life with me (Thats why I suggested the teaching)
