EBT card fraud or is it really worse?

I just got a food stamp card a little while back.. Well I was only getting fifteen dollars a month because I was employed. I got fired and went and reported it at the EBT office (Live in florida). They gave me 200 and then i was employed again. its been about three weeks and i was stupid and forgot to report that im working again. I called the office and made an appointment to go in and talk with them. I feel like ***** for this, i know food stamps are not meant to be abused and I messed up. I just hope they didnt arrest me. im a bit nervous. ill pay any fees and if i have to...
