Dear brothers:  Please get life insurance.  Right now.   With all the money AJ Johnson made in his life, why is his family having to open a GoFundme?  From TMZ:  Anthony Johnson's death has left his family scrambling to find a way to cover his burial -- something his wife says isn't being made easy with the empty lip service they're getting.  Lexis Jones Mason tells TMZ ... she and her family have been getting a ton of what she describes as "fake love" left and right in the wake of her husband's sudden passing earlier this month ... which she's quite upset about, seeing how she needs financial assistance.  This interview's heartbreaking -- Lexis fights back tears as she explains how the Johnson family has started a GoFundMe, but have come up way short of the $20k goal they set to properly bury him and give him the service he deserves ... so far raising less than $800.  And, in spite of people apparently telling her they'd donate and chip in ... Lexis says much of that just hasn't materialized, and seems folks would rather lend emotional support instead of actually helping out in a way they really need right now.
