My mother has always been a bit of a narcissist - if ever I was to get injured as a child, she'd worry about how it effected her - when I got hit in the face with a ball and had a huge black eye, she worried about her holiday photos. When I fell - she'd worry about having to replace the clothing I was wearing. When I told her I was sexually abused by a family member, she worried about how that would effect HER relationship with the rest of the family if it came out. When my son got badly hurt and needed to go to A&E her first concern was how she was going to get her shopping if I wasn't available. You get the picture!
It's been a constantly rollercoaster of guilt and frustration and I'm sick of it.
She has a habit of calling up elderly family members, telling them I'll take her down and then when I say I'm busy (like, I have an exam that day type busy!!) she'll say "oh, I'll tell your old, ill grandfather that you don't want to see him today then" 
Anyway, I started university last september doing a degree. My mum has never been that supportive as - she worries about how it will effect her if I'm needing more childcare. So, since uni started she's been in a mood about me "never going to see her" and apparantly not bothering with her anymore. Last semester I was revising for 3 exams whilst writing an assignment AND working 37 hours a week and she said "but you have a two days off a week, why can't you come then?" because I'm fooking busy!!!
To the point - these past few weeks she's been in a major mood with me. Everytime I ring up she puts on her "oh I can't be arsed with you today" voice and makes me feel like shit. I suspect it's because she knows I've very recently started seeing someone and she thinks I make more time for him than I do for her. Anyway, last week I called her and asked if she wanted to come to York with us for the day. She agreed and then called me up on the day before to say actually, she works at the charity shop that day so can't make it. She then asked why I couldn't choose another day so that she could come so i said "because Tuesday is the only day I can do. I'm at uni Monday and thursday, cinema with the kids wednesday and have appointments on Friday." she snapped "oh well I just won't bother then". Que - me feeling shit again.
Yesterday I called and asked if she fancied doing something today - she replied "oh, didn't really fancy going out tomorrow" - I then hear from a family member that she's complaining about me never taking her anywhere now that I'm at uni and have friends."
So this morning I ring and say "Leeds Armouries - next week, you fancy it?" and she says "what day?" - I say Tuesday and she snaps "I'M AT THE VOLUNTARY WORK TUESDAY ARNT I!" so taking a deep breath I say "wednesday?" and she signs and says "I work there wednesday too, you know that". I then say "oh well those are the only days I can do". She then huffs "well I can't go then can I".
AIBU to be utterly fed up of being spoken to like a piece of shit constantly because I can't organise my life around her???
