I chose to turn down an assistantship to the university I currently attend and opted instead to work full-time (for the university) and take advantage of the tuition discount. My reasoning was that I'd be able to clear out my debt (something I've almost accomplished) and save money for when I go to PhD school. It was a good plan, and I still think it's the right one.
However, the next group of my friends are starting to get their acceptance letters and offers of assistantship from various universities. Here I feel the pang--again--that I'm not a full-time student and am not on assistantship. I'm not a part of the English MA student community here because while I have classes with some very nice people that I talk to on a semi-regular basis, I don't share an office with them, I don't see them everyday, and I don't have the same problems as they do. I'm not teaching, and I miss that. I'm not in school full time, and I miss that too.
While I still feel like I'm on the right path, I'm starting to wonder if I maybe should have just taken the risk and jumped into the assistantship, even if it meant putting me further into debt instead of allowing me to extract myself. I'm still not sure. I think it may have been a situation of my being happier for present, but ultimately more miserable in the future, as I faced insurmountable challenges...
Basically, I'm jealous of all my friends who are getting to take the path I chose not to take. It's as simple as that.
