I was diagnosed last 2015 with Tuberculosis. I am now cured and it's been 2 years already. I am now more conscious about my health because of what happened. It was unexpected.
Now if ever i feel something pain/uncomfortable anywhere in my body, even if a slight headache, i'll start panicking. I am like you as well that if i feel something i will google it up but then my anxiety gets worst.
You know, if you've been sick before you don't want it to happen again because health is important. When our health is affected we cannot do anything and the worst, if we are very sick, the thought of dying will never leave you alone.
Being stress plays a big part of our health but we cannot avoid it because it's something important to us, right?
