Wasted 1,100 dollars and feel stupid

Spent the last year saving as hard as possible got up to 14,100, my dog got sick and I took 1,100 out expecting the vet bill to be really high. Turns out it was under 200. Instead of putting it back into the bank I've wasted pretty much all of it on nonsense. One of the reason I did was I was expecting to get a decent amount back when I file my taxes. Turns out I won't be getting much back at all. So I wasted almost a month of saving for no reason at all. Still have 13,000 in the bank but feel like an idiot. 😔
