Hey! I know this time is so stressful, and I hope you’re taking care of yourself in whatever way you can. I can offer some insight from my own admissions experience if you believe it’ll help. I applied before the priority deadline and was admitted on 3/1. I got an email from the LBJ School that afternoon informing me of my acceptance. The “letter” was attached to the email, along with some other documents about quant readiness and admitted students day. A few hours later (around midnight, weird), I got a generic email from the GIAC informing me the university had made a decision on my admission and to check my status page.
Regardless of your results, I applaud your for putting yourself out there in a tough application cycle. I hope things work out for you!
