Cautious or phobia?

Being all cautious and prejudice can be fatal if you dunno how to control it...

Yess, I've been too cautious to see that it's not nescessary to worry too much. Cuz :

1. nothing can be solved just by worrying.
2. it makes you stress even more.
3. you have such negative thoughts.
4. this negativity will somehow turn you into a lunatic who cannot use their rationality.

Here was what happened ~

I had trouble with pooping since like forever, it's not constipation. It's more like it's hard to get the poo out. So I had to strain harder. I know this cuz I am not much of plain water drinker. Padan muke..sape suh x ske minum air (org lain bergalon2 seminggu, aq leh pakai satu galon 1 bulan). 3 weeks ago, I had pain from pooping. It hurts exactly right after the poo comes out.

On this very morning, I bathed and had pooped. It was a bloody one. You know how I feel about it, I got myself thinking that I have rectum cancer or something. You know my aunt died of colon cancer right? Colon cancer is genetically acquaired. So I decided to go and see a doctor and check myself out. On the way there, I though about things like death and all.

So, I was set up to see Dr.Hardyanto (the doctor who treated me when I had my Dengue fever). As I was waiting for him (he did his bed to bed round), I called mum and told her what happened in a sad tone, I cried and the nurse could hear it.

Dr.Hardyanto checked me up and did rectal touche examination. He said I got hemorrhoid. I was relieved , thank god.

When I got home, I called mum and got informed that she will be taking the 2pm flight today to jakarta. I was like waaaaaattt???

This is not the only story about me being sick and diagnose something serious-death-sickness. I had rash on my breast and I though I had breast cancer. Could I have a phobia of cancer?
