<human>: I have been working at my job for around six months now and whenever I send emails, my name shows up as my legal first name. I have never gone by this name, but instead my middle name. My mom named me this way intentionally because she liked how the flow of my full name sounded better with my middle name, well, in the middle.

I had spent a good while just bearing the fact that people in the office knew I preferred to be called by my middle name, but after many conversations with workers outside the office, I have noticed on many occasions that people completely skim over my preferred name. 

So about a month ago I decided to contact our in-house IT guy about my email display name. He promptly replied that he could not change my name to a "nickname" and that by doing so, his code would break every day the "nickname" in place and it would create a lot of unnecessary work for him.

I may be overreacting, but this has started to really bother me because it feels that my place of work does not care enough to make me comfortable.

But recently I noticed another thing - many people in the office do indeed have "nicknames" for their email display name. IE: Chris vs. Christopher and Ally vs. Allison

And when thinking some more, I remembered how the IT guy had no issue when my email name was spelled incorrectly when I started working and promptly corrected it. 

So here I am, getting frustrated with IT and feeling undervalued as a team member at a job that I otherwise enjoy and I would like some advice as to where to proceed from here.

Could you distill the essence of the text into 1-3 sentences?
<bot>: I do not go by my legal first name and my work's IT will not change my email display to that of my preferred name.
