I know. The title makes me sound mental.
My mum has 5 children. I am the oldest. I have 4 siblings aged 21, 18, 16 and 12.
We all grew up in a very dirty, moldy, 3 bedroom council house, my mum never showed any emotions towards us kids. I don't ever remember hearing her say she loved me, not once. She used to stay in bed sometimes until 5.00pm, way after we got in from school. She married my step dad when I was 6, my two sisters (21, 18) and I were born as a result of her previous relationship. She then had my youngest two siblings (16, 12) with my step dad. He hated us 3 oldest girls. We hated him.
As said before, my mums house was really quite disgusting and even to this day, is quite disgusting, despite only having two children living at home. My mum and step dad have never worked a days work in their lives.
My mum has never hurt us, but we was often not fed, I was always told I was thick, just like her. I left home to be with my (now) DH at 16. We now have a lovely life, and an amazing 5 year old DS. Steady job, etc. Except mum still manages to bring us all down. She is great one minute, offering to help, buying DS things, sweet tone. She doesn't dare cause anything to my face because shes scared DH will phone her and tell her to shut it for the 100th time . Now she slags us all off behind our backs etc.
For just under a year, shes had a pet parrot she absolutely adores. She has spent thousands of pounds of her benefits on this parrot. She spends £30 a week on luxury food for it, and lets my younger siblings starve or live off toast and cereal. She buys the bird so much - while my younger siblings walk around in rags, they both look incredibly scruffy.
Today though, I saw red. 
Its the birds birthday. She has bought the bird so many presents (about 20) wrapped them up and built a huge play cage. Then I saw on FB, a huge spread of party food (normal human food) spread out and 1st birthday banners. She's throwing the fucking bird a party. She doesn't do this for my poor DSiblings. She jokes we're jealous of the bird
.
She even gets fussy at her grandchildren if we go anywhere near the bird cage or if they're to loud.
Am I missing something here? or AIBU?
Am I being as pathetic as my mum thinks?
