hello everyone, 

please i need some advice. i found a lump behind my ear a few months ago and told someone, but they dismissed it as a lymph node that would heal quickly, so I completely forgot about it. However, months later, i was just touching my face and i felt it, it's still here. It's hard, solid and it doesn't really move and it's roughly about pea size. When i'm alone i research it and find that it is a symptom of cancer. Everytime I think about it I burst into tears- I'm terrified and I don't know what to do, i tried to show some people and they told me they couldn't even see it and that i'm overexaggerating. But i can feel it, i know it's there and i'm too afraid to get it checked out. Does anyone know what it could be ? Has anyone experienced this ?? Please help, I feel like I'm losing my mind
