hi, I have OCD. when I was younger, I was obsessed with straight line, always when I had any problem abut I was obsessive thinking, when I though that it is not so important, because there is straight line. So this line was very important form me. When I had doubts, that those line is possible to exist, I felt in panic. is that any disorder/ mental illness? How common are those disorders? DoYou have also obsessions with straight line?
