I feel like a complete fraud.

It only takes one small error in my code, and one small request from a reader to see the code, and my entire work could go to waste. One small error is enough to undo 3 years of work in an instance. Every time I get an email asking about my published work, I am in a complete panic that they will find any errors.

I know there is one small error there, that I discovered only after my work was published. I think it doesn’t affect the results too much but I’m not sure, and I can’t afford to find out.

I am exhausted, there is so much work and the more work I do the more of a fraud I feel.

I tried to improve myself. I managed to increase my health and fitness a lot, but it really doesn't matter if my entire career could be down to one simple error. There is off course no reason to think that there aren’t any other errors which I have not discovered yet.

I’m sorry for rambling. My mind can’t be shut off.
