Does anyone else have a ‘disgusting’ yellow pillow?

I’ve had my pillow for ages, as long as I can remember. However my mum says it’s disgusting and needs burning. It’s a bit yellow with the age of it however there are various blood stains on them as I also get nose bleeds when the weather gets too warm for some odd reason. It’s the comfiest thing I will ever own and I just can’t let it go but I feel as I move out (I’m 19 btw) I should be getting rid of it as it may deter people. Obviously I have a pillow case on it but I just don’t know.
