S.S.D.I.

Hi,
I have been disabled (Bipolar Disorder) for ten years and receive S.S.D.I. (not S.S.I.).
O have sued my mother's nursing home for neglect, harm and abuse.
If I were to win the case, would the monetary award affect my S.S.D.I. pension?
If it does, then why? When people retire, no matter their wealth they still receive Social Security benefits, don't they?
After all, it is my money which they are sending back to me.
