Your situation over the years seems to be very unfortunate. In life though as you probably know once you lose something you dedicate your life to disappears, regaining it becomes a losing battle. This may be the case with you currently. What I can say is that you have choices here, one is to start from a lower position, i.e. do the thing you use to possibly as an assistant and then when you are up to speed with the changes in the law, you may then choose to go back to where you were.
Another option is to think along the lines of what you like. You enjoyed performing in the court, maybe you can teach what it takes to be someone good in this profession. But more importantly think about what you would like to do with your life. Think about other interests you can pursue.
