Does anyone else not talk to someone they thought they'd never not talk to anymore?

I've lost a lot of people these past couple years that I've loved

A couple best friends

My grandfather my cousin

They all just changed and left me all different reasons but especially my grandfather got remarried and totally disowned me and my mom.. and we were really close with him especially my mom she still cries a lot. It still hasn't hit me fully that he will never speak to us again even though it's been years and he totally hates us and has done bitter things.. also my cousin who was like my father figure stopped talking to me and hates me now too because of my grandfather.. and then the best friends I never thought I'd not be friends with anymore are just gone like they're all just dust.. just memories..

I'm really sad and honestly fucked up from all the people that just dipped on me. I have trust issues so bad now I can't trust anyone is going to stay in my life..

Can anyone else relate? Or have u lost someone not from death but just them leaving you like your nothing ? If you can relate please comment
