It's such a pain in the A** running a clinic on my own

Approximately 3 weeks back my nurse went on her maternal leave. Hence, running the clinic became a one man show. I have to sweep the floor early in the morning, throw the rubbish, then would I be able to sit down and enjoy my cup of coffee.
Since my clinic is paperless, all new stocks needs to be keyed in the computer to update the stock. And the clinical program that i use automatically deducts the amount each time I prescribe the medication
But when I decided to do a stock check last Monday, it's such a pain in the a** as there are like 1001 medications and it took me 5 days to complete the stock check.
What I found out was disappointing. My apparently diligent nurse did not key in the new stocks that arrived, and deduct from the system for drugs that's already expired.

Just look at the amount of corrections and alterations. It took me hours a day, for the past 5 days with disappointing result.
Worst still, there are new drugs that we ordered which wasn't keyed into the system!!! That really pissed me off!
And now, I have to key in manually to correct the numbers, and key in the new drugs all by myself. Just by looking at the file the contains the invoices was really discouraging and stressed me out. Have a look.
It such a pain in the a**! I have to key in everything BASED UPON THE INVOICE, which i have to check pages by pages! I am sorry to reader if I sound a little offensive, but I need to express myself......
SHIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIITT!!!!!!!!!!!!....................
