Some background: A coworker berated me for 20 minutes back in May. I applied for a lucrative temp job, got it, and put in my notice happily. At the last minute, the job and I mutually decided to keep me "on staff;" they liked me plenty even if my coworker didn't. I ended up doing temp jobs over the summer, made some really good money. But I came back because I had to take lab for chemistry to finish my degree. So, I came back, but told them I would probably leave again come December when classes ended.
Since I've come back, I've barely worked with the coworker but even so, she's managed to irritate me. She'd irritated me for years, but it wasn't until she berated me with witnesses that I just can't seem to emotionally deal with her at all. I immediately started collecting FU money, instead of paying down my pre MMM debt (39k mortgage/10k of school loans, no credit cards), because I thought being able to pull the trigger if it became too much would make me more patient about her. There's been some turnover lately, which means this coworker I don't get along with has been shifted to working with me. I was very alarmed about this, as I didn't look forward to 3 days a week of (working with her and then) needing to decompress after [each] day with her. So, I told management we needed to have a meeting so we could air the situation with management witnesses and maybe I could improve my working environment and stand to work with her. Today, I have my F.U. money. Today, we had that meeting.
The meeting involved my supervisors going in circles trying not to side with anyone and alienating me in the process. My manager lost his temper and raised his voice at me and said I was oversensitive. I am now more unhappy with my work and wished I hadn't bothered.
I have to stay in this city until December 14th at the latest due to class. All my bills are covered until the end of January and a little into February. If I put in my notice, I am walking away from about $4000-$5000 of earned income.
It's also very possible that I could go to weekends only, and due to the nature of weekends, pretty much never interact with any of these people again until I give them notice, whenever I land that temp job. The nature of the temp work, though, could mean I don't necessarily get it until March, because winter is a slow season.
TL;DR
Bad coworker and management yelled at me (literally.) I have F.U. money till February, but may need more than that due to erratic temp work. I'm seeking advice now, because I don't want to be so oversensitive I shoot myself in the foot, but I also don't want to be working with these people who cause me to feel like my work is low worth.
Edit add Explaination:
People have asked what she's done. She actively proselytized and brought up uncomfortable conservative politics e.g "baby murdering." The one time I asked her to stop discussing such topics she told me,"I wasn't talking to you." We're not in cubicles, she's 2 feet away from me. She accuses me of avoiding work, being inconsiderate, and compares me to others she likes more to my face on multiple occasions. She's homophobic, transphobic. I am completely self motivated and work independently often, but she feels the need to micro manage me anyway because she has opinions about what should be done in what order. And whereas I'm the sort to agree to disagree, (that's my default outside of personal intimate relationships) she feels the need to actively tell me I'm wrong. Has even sought management to side with her (they haven't in the things she's brought up). Her more recent annoyance was turning off the light in the office and assuming I can rely on a small lamp to do my paperwork. I considered this last part to be overly controlling of my work environment. And since her newly found preference deviated from the norm of years of well lit office, I thought this would merely be rectified with a complaint. Instead, I was told to compromise and they're getting me a brighter lamp. Which seems absurd. The default is lights on, and they're spending money to conform around her new found preference by getting a light when there are lights in the ceiling that are perfectly useable. I suppose the flipside is they're buying me a lamp so I can see better but I still shake my head.
