My dad is 21 and has what I would describe as low level autism. She also has a brain tumour which she has lived with for a year and is on a watch and wait plan. She is unable to work due to fatigue and pain in her head. I am making myself ill worrying that her boyfriend ( who is her world ) is going to break up with her. I can see the signs. He’s become distant and is rarely at our house anymore. I don’t know what to do. I feel sick to the pit of my stomach. I know that I’m obsessing over her and don’t know how to stop. Any help or advice would be so appreciated.
