Hi I’m new to this and just wanted some advice please, last year my uncle got diagnosed with non small cell lung cancer that’s spread to his spine it’s incurable and he’s lost his mobility. Since him being diagnosed all I think about is myself getting cancer and I’m constantly looking for symptoms and feeling my body for lumps, every pain or ache I get I think the worst.. has anyone else felt like this or any advice on how I can stop my mind constantly thinking the worst 

thanks
