Is AUTHOR wrong in the post ? POST : Tomorrow morning I am sitting a 10 hour medical admissions exam (in Aus it’s called the GAMSAT, it’s the equivalent of the MCAT I think). Tomorrow night is my mother’s 50th birthday party, although not her actual birthday. 

The party has a theme which is ocean, from the moment she gave me the invite she said that it’s important that her kids dress up, I thought okay groovy I’ll be a mermaid. and let her know my idea. All sorted, right? Wrong. For the next two weeks she called me constantly as I was trying to study for this exam, with the calls usually ending in her suggesting that I hire out a costume (which I can’t afford) me saying no, I’ll be a mermaid, and her calling me selfish or implying that I don’t care about her party. 
Every time she called I chatted a bit about the costumes etc. because I knew it was important to her, and gave her advice on her costume so she knew it mattered to me. After the first few calls I did mention that I wasn’t going to change my costume and the calls are distracting me from studying. 

A few days ago I realised that if I wanted to dress up as a mermaid I’d end up being late for the party (which I’d be late for anyway, my exam finishes at 6:30pm when the party starts, and I’ll be travelling about an hour to get to the party), I mentioned this so my mum and she once again tried to force me to hire out a costume that I can’t afford. When I said no she suggested that I leave my exam early (...I paid $505 to sit this exam and only get two attempts, she is well aware of this) so I don’t end up being late. I said no, she once again called me selfish and said I don’t care about her birthday or her party and that I’m putting my medical admissions exam ahead of her party (no shit I am!). 

The hilarious part of all this is that she takes so much pleasure in bragging to all her friends about how she’s doing everything she can to help make sure I do my best in this exam, but last Friday when I asked for the day off of work so I could study/because I was unwell (my mums my boss - yay) she told me there was endless amounts of work to be done and that I needed to come in. I asked multiple times for the list of tasks that need to be done and she refused to send it to me, so on Friday like the jerk that I am I came into work... it took me an hour to do the ‘mountain’ of work that was required of me. And the drive into work is an hour so it was pointless for me to go home afterwards. 

I’m at a loss, she’s currently resorted to saying that I’ve ruined her birthday and she doesn’t even want a party anymore, and I’m worried if I turn up I’ll get harassed. Whereas if I don’t turn up I’ll get badmouthed to the whole family. I’m about 90% sure that after the exam all I’ll want to do is pass out/cry, I’m pretty sure just the fact that I’m showing up shows that I care...

AITA?
