Guys. Gals. Whatever.
Take a deep breath. The waiting is NOT agonizing - you're making it agonizing. Agonizing is absurd hyperbole.
This is a time to celebrate and be thrilled - you got through all the pre-reqs, you got your LORs, you wrote the stupid PS, filled out pages of application information, coughed up a chunk of change to apply .... you did a lot.
You should be thinking of this as thrilling, not agonizing. Believe me, the stress of waiting to hear back is miniscule compared to the stress of your first few months of vet school trying to figure out how to manage the flood of information .... then the stress of boards that you somehow have to take in the middle of fourth year when you're spending 12 hours/day at the hospital .... then the stress of your first job where you're reminded how little you really know while simultaneously managing clients that alternately love you and hate you ....
The stresses are just beginning. Don't let the application period be that big of a deal. If you have a hobby, throw yourself into it. If you have a job, pick up some extra shifts to bank some cash. If you like to travel, do it now and enjoy yourself. Keep picking up veterinary hours in case you need to apply again, and keep developing those relationships with vets and other people in the field.
Make yourself busy, and the application will go to the back of your mind. The first time around I obsessed over it and it sucked and I felt like it was awful, just like some of you feel now. The second time around I filed the application, never looked at it again, forgot about it, and was genuinely surprised when I got the interview offer - because I kept myself busy and moved on with life. I was like "oh, is it that time already?" Don't put your life on hold waiting for the answer.
Don't be First Time LIS, be Second Time LIS. Future you will thank current you.
This has been my yearly PSA. Good luck.
