letter of recommendation late

hii!

my first app was due on Monday and i turned everything on time (yayy!) and 2/3 of my LOR writers submitted BUT my 3rd one has yet to submit, am i just doomed ?? 😭😭😭 i spent $70 on the application and i feel so defeated

i have a great relationship w this writer as well! i’ve known them for about 4yrs now, they were my supervisor in undergrad and then we became colleagues after i graduated but i am no longer working at that campus anymore :((( so i felt super confident he’d write one for me and submit it on time! I did send him emails a week prior, l the week of, and the day of and he hasn’t responded to my emails :(((

i ended up texting him (more than likely unprofessional i know but i was panicking) the day of letting him know it was due tonight (monday) he DID reply but all he said was “i didn’t see the date, let me find it” and that’s all :( i emailed him again this morning to remind him but hasn’t responded, should i text him again?? this is my first ever grad app so this really bums me out that not everything was submitted on time, do i still have a chance ? :(

i really hope he’s ok and nothing is wrong in his personal life or work
