Oh Jamie. You are in total meltdown at the moment jumping from one fatal illness to another in space of hours let alone days. Please do as suggested and print out all your posts in past few weeks on here and take them to your Dr as they really really need to know just how bad you are.
We cannot offer any reassurance as you won't believe us no matter what we say.
You have no symptoms of lung cancer/glaucoma/brain cancer but you do have massive symptoms of anxiety.
