Diabetes diagnosis. Unhealthy stuff?

I know its a weird question, but i have very weird query, can you develop diabetes within a day, like i had my hba1c checked with fbs all which came normal a month ago, also i have severe illness/health anxiety , i just had very heavy dinner which mostly consisted of junk food and sugary drink i consumed a lot, means a lot on 4 july and suddenly ihave developed excessive thirst and excessive(i have severe anxiety i feel thirsty when anxious, it can be die to anxiety or is it something related to diabetes) urination although i eat only normal homecooked food and on a an diet for weight loss but just on 4 july i made a mistake, none in my family has diabetes history or heart issue, in simple form can i develop diabetes with just 1 day of eating very unhealthy stuff?? I dont have any weaknesa whatsover i workout 2 hours 5 days a week.
