So, I have submitted 7/10 applications so far and should be finished completely later this week (the remaining 3 apps have deadlines in January). Unfortunately one of my LoR writers hasn't submitted any letters yet and 5 of my schools had deadlines on Dec 15th. Every day that passes is making it more unlikely that those 5 apps will be properly considered. Honestly, I'm a bit blindsided by this and figure that the prof must be really busy at this time, because he has submitted references for me more than once before and he's always been very supportive and dependable. He even gave me advice earlier in the process this time around. I've reminded him via email and when I saw no progress and didn't get a reply I was able to get in touch with him by phone this week and he assured me he would send them in. I've let him know the urgency of the situation, but until I see those letters submitted I'm almost dying of anxiety. Any advice in this situation? I thought waiting for results was bad, but this is much, much worse!
