Haha. I was freaking out a few weeks ago about my LORs. I didn't know when/if my professors sent them. LSAC wasn't processing anything. I was checking my email/LSAC 5+ times a day. Finally they both came in within 2 days of each other unexpectedly. It was a huge relief. BTW, it took about 10-14 days from when my profs sent the letter until they were processed.
The worst feeling was that I wasn't going to go complete until they were in and everyone started getting acceptances at schools I wanted to go to
I really feel like I let myself down. I really pity all of you still waiting on your LORs. I know how it feels.
