I’m so sorry this happened to you. You are very brave for standing up. I used to be where you are. After years of self examination, I changed my career path to enable me to have a son as a single mother. It might not feel like this is a blessing but years down the line you will feel it when you have built a career outside of investment banking. I’m partly afraid for you partly really admired you for your courage.. start on a backup plan and stop interviewing on Wall Street.. tech companies also need lots of sales managers who can build relationships. Best of luck to you and your family.
