My first actual OCD thought that I had was regarding harm and knives. I felt exactly like you did about windows at that point- I was terrified to even look at knives or get near them. I thought I was going to hurt someone I loved or my pets or myself. I thought I was going insane! Then suddenly, I listened to music or watched TV or whatever and it went away.

Those kind of obsessive thoughts, for me, are long gone but they're replaced with something just as bad.

I'm not sure what to say but I completely know how you feel. For that particular issue mine just kind of went away, but then again I'm on antidepressants (Escitalopram) so maybe that helped...
