Hi Guys.

One thing about myself that confuses me is:

After receiving some pretty significant bad news, like 8/10 in seriousness, I remained calm, thought rationally and wasn't to affected by it.

But often small minor things in my life that won't mean anything in 10 minutes, yet I get annoyed and flustered.

This is somewhat paradoxical and something about myself that annoys me. How to fix it?
