How to write an apology letter and ask for forgiveness?

Here, I'm sorry to read you my apology letter for drunken fighting. I really feel guilty and blame myself for my drunken fight, which caused my colleague Wu to be slightly injured and seriously damaged the good working atmosphere of the company.

Looking back on my mistakes: I broke up with my girlfriend some time ago, which caused me to be unable to get out of the haze of lovelorn. My mood has been very low and I began to become irritable. I happened to meet a colleague's party in this company. I didn't plan to attend it at first, for fear that I would lose my temper because of drinking. But at the repeated invitation of my colleagues, I attended. During this period, I met my colleague Wu, and I had a little holiday (). During this period, my colleague Wu mocked me half jokingly and half seriously, which made me feel very excited. I waved my fist at my colleague Wu with the help of alcohol.

Now, after deep reflection and self-blame. I deeply feel the seriousness of my mistake, which has caused so much harm to my colleague Wu and greatly affected the good atmosphere of the company.

Now I will review it as follows:

First, frustration in emotional life is brought to work, which is a manifestation of lack of self-control and deeply feels one's own shortcomings.

Second, hurting colleagues with alcohol is a serious violation of the personal rights and interests of others and a great violation of discipline and law.

Third, I lack a sense of crisis. If I had planned ahead and resolutely refused to attend the party, although it might ruin the interest of my colleagues, such a serious incident would not have happened.

Now that the mistake has been made, I want to apologize to all the colleagues affected by this matter, bow deeply to the unit leaders and say to everyone: I'm sorry! I will try my best to make up for my mistakes with practical actions in the future.

Hereby:

I'm very sorry!
