Don't tell anyone, but I used money my mom gave me for the vet for gambling.
How much did you lose?
$750 -- I told her that it was for the veterinarian and for school tuition.
It is wrong to gamble with money for education. You should repay the lost money you didn't use towards your education before she finds out.
I'm sure my mom wouldn't find out.
She'll find out when she gets the unpaid vet bill and calls the office to complain. You clearly have a gambling addiction. The sooner you get help, the better.
