I got a new disease this Friday. But it's not serious.

I have been scaring all insects and bug. I can't catch bugs, even though it's a little. Sometimes I catch flies with loud scream. My mom has been talking to me it's a disease. But I thought about her saying lightly. I also didn't believe there is a insectophobia. And this Friday, finally I heard that I have a insectophobia. It's not too bad, but the doctor said it was a little bit serious. I had thought that everyone who hate bugs can't catch it and scream when they saw them. Have you knew about a insectophobia? I was surprised this disease real exist.
