Going to school again???

Right now I'm working as an ECE. I graduated high school in 2015 and went to school to be a dental assistant right away but had to drop out two months into the course due to medical reasons. Last fall (2016) I started my childhood education course and graduated in June of this year. I like my job but I feel like my medical issues get in the way and make it difficult for me. I'm thinking of maybe going back to school in 2018/2019 to Major in History and become an anthropologist.

I feel like I'm just jumping around in hopes of finding something but just putting myself further in debt?
