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?
