@Whatayear2023 Oh that is such an awful shock for you.
Of course she was your 'Mum', she brought you up from a few months old.
My Brother's best friend from childhood was very close to his mum, and on his Birthday his mum literally collapsed into his arms and died.
He saw her begin to fall, and caught her by some miracle, but said ''I knew she was Gone the minute I caught her''
He too obviously did what you did.
It was extremely stressful for him.
He's ok now a few years later, but it hasn't been easy.
Your 'family' sound horrid to speak to you the way they have been.
It's a shame your Mum didn't change her Will, at least that would have given you some security.
I lost my mum as a young child, and do like to think that she looks over me, like a guardian at times.
Please don't ''Try to join her''..she wouldn't want that.
Don't try to stop your tears.
You were a lovely Daughter to her. ♥️
