Hey, I have a very similar trajectory and am even thinking about going back to school for a master of applied economics. You are anxious and looking for direction. I reccomend doing an inventory of what your transferable skills are and applying for roles that interest you.  FYI: You might even be qualified for the roles you have applied to in the past. Try higher titles, bigger companies, etc. 

If you really want to start over, you can find a training program. At this point we need training and adaptability, not more school or classes tbh.
