My difficulties are diagrams of any type, formal logic, mathematics etc. This leaves me with Sociology, History and English. None of which interests me the least.As a past philosophy major myself. I think ANY of the social sciences would be a great transition. If you've taken any type of logic, epistemology and philosophy of mind classes they would be a great help. Those help you develop theories and break down everything to an elemental level.
In Philosophy, I struggle with the Fitch style calculus. I am like a monkey reading the book. You can put me on an island for 2000 years with it, and I would still fail at any attempt to demonstrate logical proofs.
I almost learned how to use a truth table functionally, but not fully, and I forgot it by now.
