Hi, I'm getting really scared I have been seeing 13 for the last 6 months and I see it everywhere TV, computers, clocks and even when I counting things sometimes it adds it to 13 and plus me and ex boyfriend statred going out on the 13th and after I started seeing 13 we split up after 2 years and half and also since that time I have lost my job and had some friends prombles.
