I was diagnosed with BPD after 2 suicide attempts. I dropped out of that year of uni with plans to return fully the next year. The next year was even worse. I was spiralling. Over Christmas break that year my mom and I were at the mall together and we walked into a clothing shop. She casually started browsing the maternity wear section. I said to her "I realise that some of these designs are nice and all but I've never heard of a non pregnant person wearing maternity wear." She said "I am pregnant" as if it was the most natural thing in the world for a 48 year old woman to be pregnant...

I was raised by my grandparents until I was 13. Being without my mother for so long (she seldom visited), made me quite content to be without her. But with my grandparents failing health she insisted that I come live with her. Grandparents died 2 years later. I was never the same and I hated staying with my mother and I was severely depressed but said nothing.

However our relationship improved when I moved out of home and went to uni, though my mental health was rapidly deteriorating in the background. Until it all came to a climax when I was 20. Then the very next year she has another child and I'm back to being way down on the priorities list in favour of the new infant - while I was struggling. I needed her. She dedicated her time to falling pregnant by expensive and  unnatural scientific methods and then had a baby that took up all her time. I'm very disappointed in her. Then she has the audacity to say in the future she hopes I will pay my sister's school fees. No. Fuck You! 

Tl, dr: my mother very deliberately replaced me with another child by means of ivf when she was already too old to have a child and all of this happened after she had hardly paid the slightest bit of attention to me in my childhood. Cherry on top: all of this happened when I was at the worst of my mental illness so she had zero energy, patience or time to support me, the child she never even raised! 

Sorry, it makes me bitter when I think about this.
