I'm a recent college grad who finally got my first real programming job. For better or for worse, I am extremely attracted to my boss and have quickly developed feelings for her. This seemed awesome at first (like getting the hot teacher in a class), but now I've realized that this have made things very difficult. A few examples:

* Whenever we are in the same meeting, I am always stuttering and making a fool out of myself
* Sometimes she will be wearing an outfit that will make it extremely difficult to concentrate on work. (She sits a few cubes down from me and I can see her from where I'm sitting). Coworkers will catch me zoning out staring at her.
* Last week when my coworkers were making fun of my boss, rather than joining in or remaining silent, I got really angry and aggressively defended her to the point where I made things awkward. They now only talk to me about work related stuff.
* Sometimes I find myself getting irrationally jealous about stupid things, such as seeing her socialize and laugh with other coworkers.

I fully recognize that these feelings for her are unprofessional, inappropriate, and bordering on infatuation. My question is: what should I do about this? I've seriously considered quitting, but this could be a horrible career decision considering that this is my first programming job and I've only been here for two months. Is it inappropriate to ask to change teams or move seats without specifying a reason? Would there be anything at all gained by admitting to her or somebody else (like HR) that I am attracted to her?

Just want to clarify a few things:

* Under no circumstances am I looking to try to pursue a romantic relationship with her. Not only would that be highly inappropriate, but she's way older than me (probably the same age as my grandmother).
* Despite everything, I still feel like I'm performing decently at work. I'm not doing my best, but still doing well. My boss has complimented me several times on the quality of my work.
* To elaborate more on the incident with my coworkers, basically they were making fun of her weight.
