That's a tough situation.
Is your wc claim closed or still active/open/ongoing?

If the meds and pain caused the depression -was that added to the claim by your doctors?

my thinking-
Pain from injury = medications - plus depression from changes in life and activities and wc claim!

Did you have any depression before this?

just some thoughts on it.

A lot depends on how your doc writes and records the injury and relate the depression to it.
and of course proving it all.

do you have a good comp atty on your side?

can you get a re-evaluation of your limits- due to TOS & RSD?
