My sister for as long as I can remember has been demanding of my parents attention. If anything happens in my life she creates so I don’t get any help. My parents don’t realise or want to admit this is the case. I’ve had to create my own support system after I was abandoned to look after a toddler post op and tore stitches open as a result (this is one of many instances including miscarrying, post partum depression, chronic illness which requires surgery which I have dealt with alone). My sister will often tell my parents they’re not allowed to help, for example, a couple of years ago they offered to lend me money to move house but then just as I offered and accepted an offer on my house she became upset and they withdrew their offer. She has had vast amounts of money from them as they chose to send her to private school.
More recently she has been shouting at them whenever my name is mentioned, this week my mum has been at my house twice telling me about these incidents. I have always been last in my parents lives after my sister, their new partner, their careers etc . I have done a lot of emotional and practical support for both of them over the years. I no longer expect or want anything from them. I realise that their favouritism of her now extends to her children as they have provided a huge amount of childcare and tutoring for them. My children are starting to notice this and realise how unpleasant the dynamic is.
I don’t know how to continue, I’m struggling to sleep and feel guilty just for existing. I can’t cope with the results of these explosions for my sister and my health condition which is already poor is being affected by the stress. Any advice gratefully appreciated.
