I agree with BreadandJelly. Try to get off the internet.
I think we are all susceptible to this type of being a hypochondriac. First of all,so many illnesses have similar symptoms.Or rather,a vague amount of symptoms.It's so easy to get paranoid thinking,"I have that!"
It's called being impressionable. If you even say the word "EYE" to my husband,his eyes start bothering him.Watering and itching...even though nothing is wrong with them.You have introduced the power of suggestion,and for many people that is huge.
Otherwise there would be no such thing as a PLACEBO effect.
There is a whole world out there.Breathe it in.Get off your computer.Your brain needs to be distracted from paranoid thoughts.
And just remember,the internet is FILLED with false information too.You can't be sure if what you are reading is correct or BS most of the time.
