looking at the history and mri
report it seems that you have significant injury
to the back but you are quite lucky that you may not require any surgical management for that at this stage.
Instead worrying what has happened you need to plan your future so that you have less pain.
all you need is good physiotherapist a proper size taylors brace and lifestyle modification so that the injuries wont hurt you in future .
take a opinion of good spine specialist for that.
