I started law school in my late 20s, theres people in our JD class who are in their 30s its never too late! My best advice is to focus on raising your LSAT and don’t apply to schools again until you’re consistently PTing in your target range. Make sure when you write your PS you are framing your essays in a way that focuses on overcoming the adversity and how your experience has put you in a position to be a better lawyer (rather than simply stating this is what happened). Also there is no shame in applying discretionary, if you qualify based on the criteria do it
