How do you deal with an egomaniac entitled elder sister?

She’s 5 years older than me…. is the middle child…
always has high ego and attitude…. doesn’t answer when u ask her something always acts like a victim…

in childhood she used to laugh at me after punching me in the gut… (when u get punched in the gut u feel like u cant breathe that was funny to her)

she would throw things at me and then act like a victim in front of my dad and family.

If you even joke with her she takes it as “disrespect” but she can do anything Lmao.

Shes always throwing shades at me being passive aggressive and condescending.

Be it my hair or my clothes anything. She can’t digest any good thing about me.

One day she said before u were born dad used to keep me in his lap but then u came…

Shes 25 now Lmao yet immature and childish.
My older brother is 2 years older than her but hes so mature and never acts arrogant or throws attitude or tantrums.

She always finds a way to ruin everything.
