Phobia of the numbers 11 and 13

I have a Phobia of the numbers 11 and 13. I started seeing 11 everywhere when I would so something bad and when me and this girl I was best friends with would fight. We stopped being friends for a few months and I saw 11 everywhere and when we started being friends I didn't, then she told me she always see's 11.

Then I started seeing 1113 together. Literally everytime I looked at a clock it would say 11:13. And I would see it everywhere. Then she told me she had a dream and on the clock when she woke up it was 11:13 and she has no idea that I had been seeing the numbers. I can't explain what it is. I would like to know, because it gets annoying sometimes.
