How to write a criticism about sleeping in a hotel at work?

I write this critical letter to you with 120,000 guilt and 120,000 regret. I feel deeply guilty and uneasy about my sleeping behavior. Here, I would like to make a profound review to the leaders:

Through this incident, I feel that although it is an accidental thing, it is also the inevitable result of relaxing the requirements for myself and lax work style for a long time. As the acting monitor, be strict with yourself! However, I can't restrain myself well and sleep at work, which has brought bad influence to other colleagues and can't take the lead; Although he failed to cause a safety accident. However, due to my dereliction of duty, it brought serious security risks to the company. If there is an accident, the consequences will be unimaginable ~ ~ ~ This also shows that I don't have enough sense of responsibility for my work, and I don't have the ideological motivation to do my work better and by going up one flight of stairs. In my own mind, I still have the idea of muddling along. Now, I deeply feel that this is a very dangerous tendency and an extremely important sign.

Therefore, what happened this time not only made me feel ashamed, but more importantly, made me feel sorry for the trust and concern of the leaders.
