I'm about to be fired, if I make one more mistake, and it's only a matter of time before I make that mistake. I'm so angry at myself. The boss and my coworkers think the worst of me. I know they're right, but I'm still angry about it.

I'm not going to have the opportunity to defend myself, so I want to do it here:

I'm sorry for all the things I did wrong. Many of them were honest mistakes, but I realize that you cannot allow them anyway.

I am sorry for overstepping my bounds at work. I was not doing it to weasel out any of my coworkers or usurp their positions. I just wanted to be helpful.

I am not bored with my position, nor do I think I'm too good to do this job. I like working here, and while I do eventually want to work up to a full time position, I find no shame of being where I'm at. I do want to be open to more opportunities, but people don't seem to think I am good enough for them. I understand that.

I want to be a good employee. I am trying to do better. I know you'll be saying I'm not trying hard enough, and I know you're right. I should be trying harder.

I cannot promise that I won't make these mistakes again. I will try with the best of my ability to avoid making stupid mistakes, but given my track record, the best of my ability may not be good enough.

I care about this job. I want this job. I am appreciative of this job. I do not think I'm too good to work. I want to earn my own living and be a useful, productive, gainfully employed person, and I am trying very hard not to make mistakes or draw attention to myself. I don't know why this is so hard for me.
