I'm in college a few hours from home (so hard for me to go back) and to get a research job I need a few teacher recommendations... from teachers back in high school. I feel like I don't have a huge amount of teachers to chose from, I emailed one of my teachers (the teacher in my same area, I did very well in the class) a week ago explaining everything but still haven't gotten back a reply and I kind of need this recommendation soon. Should I re-send the whole email again? What should I do? I don't have their phone #, nor can I go back home..
