<human>: So I'm going to try and keep this short, I'd just like some advice from 'the people on the internet'... 

I've recently started a working holiday in Australia, arrived in Sydney about two weeks ago and looking for a job now... This is stressing me out quit badly, but that's a whole other discussion... 

Me and my mum [53F] have quite a good relationship, I also lived back home for a while before I came here to save up some money and even though she can be a bit overbearing, she's been incredibly supportive and a great mum in general. Before I left, she had already told me she would like to come and visit me, which I obviously think would be very nice, even though it also stresses me out a bit since I don't really know where I'll be during the year or what I'll be doing, but I'm happy trying to organise it a bit... 
However, today she asked me whether she could come and visit for Christmas... I know she'd really like to cause we don't have much family and she'd probably spend some of the holiday time alone, but I'd rather have her come and visit me another time.

Thing is, I'm renting a room in a house with quite a few people, so I'm not sure if they'd appreciate an extra person for 2 weeks. I'm also pretty stressed out about trying to find a job and being in a new country in general and I feel like I'd rather tackle those issues first and see her when I feel more comfortable... 

For now, I've told her I was going to check with my housemates (which I will obv), but I know she'll be very disappointed if I say I'd rather postpone it to another time. I feel like I'm being a horrible daughter right now and I'm just wondering whether I should suck it up and just tell her to come visit?

Can you provide a brief overview of the text?
<bot>: mum wants to come visit me in Australia for Christmas, I feel a bit stressed and pressured and would prefer a later time even though she'll be very disappointed, am I being a horrible daughter?
