It could well be deep rooted, more than you know.
It's hard to face your fears but sometimes we have to, so we can overcome it. I am frightened of death and/or dying of heart disease. It terrifies me because my aunty, grandmama & poppa all died from it and my aunty died young so it freaks me out. I used to have panic attacks about it after pop died but I slowly got over it.
The best thing to do is think logically, which is what I did and I'm not as worried anymore, like I don't think about it every day.
Like I said in an earlier comment way back, you might need time alone or go somewhere nice - Away from Newcastle & away from people.
