PS One last afterthought!!!
Would you consider doing a Masters in Counselling plus Creative Writing?
A Counselling qualification might help you to target marginalised communities - both giving you certification and helping you to hold boundaries emotionally.

I remembered that you say you have ADHD, and I think this wouldn't be an issue at all counselling/ teaching marginalised communities but it might be an issue with the large class sizes in mainstream ed?

You would make a great counsellor if that floats you boat at all, because you are sensitive and accepting! Just my opinion...
