At the end of the day at work, we have to balance our drawer and make sure we're not short.

I have trouble reading the numbers, so I always come out as short. It says I'm short on a certain amount but when my boss/co-workers check it themselves, they see I misread something or I forgot to count something(that's more on me being clumsy). It's been happening for a good while, I want to improve because it takes up a lot of time, I want to be good at my job, I want to be better at it, everyone is so nice and patient with me, although I feel like everyone hates me. I know I will eventually get good, I will be good at balancing, but now I'm just bad at balancing my drawer.
