So i found out 5 weeks ago my mum has terminal pancreatic cancer which has spread. I cant cope!!! I cant be around my mum to help her in the ways my sisters are caring. Today me and my sisters had a massive fight, saying I dont care I'm a *** daughter to my mum cause I cant see her like this. My sisters both have a family and both have a really good relationship with my dad. I dont have that at all the only person I'm close with is my mum. My mum knows I'm there for her. But my sisters and family make me feel the worst person in the world. But I just cant cope with it. Is this all normal
