Feeling so dumb

So... I really fucked up 😅😭 I did one of those like one week free trials on an app I got, it’s like a calorie counting app not that serious, it said like one week free trial and then $50/year...well me being 20 weeks pregnant with a 9 month old I can’t even remember what I ate for breakfast most days🤦🏻‍♀️ so of course I completely forgot bout it. Got charged $50 2 days before pay day, obviously didn’t have the $50, now have to pay $30 overdraft fee. Ugh I feel horrible because it’s not even my money, it’s my fiancé’s money (I’m a sahm) 😫😫😫 i didn’t plan on actually ever paying for it, I forgot to cancel it 😣
