I always suspected I had siblings, but my mother would always say that I didn't. A few years ago from an unrelated matter a bit of paper confirmed that I had 3 other siblings from her from a different father, apart from my brother, with no other information such as names. I know it was a different father because she met my dad as a one night stand, who I have met in person before. I don't have the bit of paper anymore, but it also revealed that she had changed her first and second name from her birth name to a new one, which was a surprise to me as I had always known her as Susanne Roberts (fake name). When I confronted her with it, she shut the conversation down and told me to never mention it again. She added that my life would be in danger if they or their father knew I existed. She has collected photos of my brother and I growing up, and I can see photos of her from when she was a lot younger with a young baby, that she had told my brother was him but clearly isn't, as she had him at 30, and in those photos she looks older. I noticed that but he hasn't. She has told me all sorts of stories throughout my life about who she was and about the father, but the stories would change, it was clearly made up and I want to know the truth. I remember she could be very cruel to me when I was a young child and had a diagnosis of bipolar disorder that she kept from me that makes sense of my experiences. She has always said that I was making these stories up about her and has sort of convinced me that I was crazy throughout my life. When I told someone about these things, she kept the narrative throughout that I was making stories/getting the wrong end of the stick, I was known throughout the community as the deranged child who would run away from home and make up stories, as we had a nice house, and were comfortable. Is there a way to find out who my family actually are and get the truth. When I spoke to my dads mum who didnt know about these children until I told her, and she said that she knows my mum was abusive, so she thinks that she did something terrible to her children which is why she left without them and changed her name. She also thinks my mum told me that my life would be in danger to try and stop me from going to find out the truth
