How do I get past this?

I don't text or ring my parents for a reason.

They have this knack of making me feel like the worst daughter in the world.
If I don't contact them, they then will purposely not bother visiting me even though they're coming to see my brother in the same town.

They're blatantly now all about my brother's children. Have no interest in mine. Will buy birthday/Christmas presents but out of duty, not love.

I was a middle child. My older sister was sent away to boarding school. My younger brother was the son they always wanted.

Still now as adults they make me feel like that unwanted, ugly, fat child.
I was told I was fat for several years. Would amount to nothing and was useless.

I need to draw a line under my past but it's so difficult when you cannot confront your parents. They're so emotionally distant/neglectful.

FFS!
I spoke to them yesterday on the phone. Now I feel as though I've gone ten steps backwards 😔
