My father died two weeks before my sixteenth birthday- mid way through my year 11 GCSEs (I am now 18 and start uni in September). He was an older parent with children (15+ years older than me) and due to his age I always subconsciously knew he would die when I was young, but it didn't make it any easier when he was diagnosed with terminal cancer (he had a brain tumour). My mum, who I have never been as close too, told me it wasn't cancer, despite my olderr brother telling me so. She didn't make it easy when he was ill and I will never forgive her for the things that she did, but I am now struggling and I don't know what to do. She hasn never been there for me, only seems to care when she's in front of other people and never takes an interest in me. I also want a relationship with my dads other children, and although she has never denied me this, she make sure it very difficult as she will slander them to me and due to her actions when my dad was ill, they do not want a relationship with her and she can't understand why.
Quite honestly, I feel alone (even though there are so many people around me who love me). I want my mum to be a real mum but that will never happen. I am asking for advice now as I want a closer relationship with my dads children but I don't know how. They all have their own lives and whilst I know they care, I don't get to see them often because they live so far away. I don't want to be a nuisance to them but I want to have a relationship with them. I also don't know how to go about it because my auntie cries everytime she sees me because I remind her of dad so I don't know whether to just leave them because I don't want to cause them more pain.
