is history repeating itself?

it's only 10:30 and things are already starting to go wrong!!! we just had a phone call from my auntie and she's going into hospital to have a head scan because she's been getting headaches over the past few weeks. this is so worrying considering what has happened in the past!! she's has to go to the MAU (medical assessment unit) at Shrewsbury and this is the place where my grandad was when he was first diagnosed :( I'm worried that history might repeat itself and the same thing is gonna happen to her. I was researching cancer one day, and I read that it can be passed down through generations and I'm cautious is case my dad gets it or even if I get it :/ after everything my family have been through, we didn't need all this shit :( I'm still grieving over my grandad and I just cant go through anything like it again. so yeah, and I have my doctors appointment later so I'm worried about that as well. I didn't need all of this extra aggro in my life right now and I'm fed up of things always going wrong in my life. why can't I ever be happy for once and live a good life without things completely fucking up :(
