I don't have OCD, but anxiety and depression.
I get intrusive thoughts of hurting DD, by accident - like knocking her over, or dropping a hot drink on her - or on purpose, just now she was on her hands and knees arching her back backwards, and I had an image of forcing her head backwards. No reason at all. It's horrid and makes me feel sick.
I also relive moments where I've embarrassed myself in life, even from when I was a child. It literally brings me out in a cold sweat. I was a really shy child and I remember once being in a queue for an ice cream, I was 3 or 4, I decided to be brave and turned to my Dad behind me and said 'daddy can I pay for the Ice creams?' except it wasn't my dad, it was a stranger - dad was next to me. The stranger said something funny, and a few people laughed. I vividly remember the whole thing and it plays over and over in my head like a movie.
I walked to college along a main road, narrow pavement, terraced houses with front doors opening right onto the street. I used to obsess every day about a lorry losing control and hitting me. Every day as I walked along the road it was all I thought about. I would try to pick out the houses that might not have locked doors, or where people often seemed to be home where I could maybe have an 'escape route'. I'd always walk on the side facing the traffic so I would have warning if it happened.
Before I had children it was often that I would have awful images of my future potential children being kidnapped, or killed in an accident, or going missing. My Dr laughed when I told him that. It was really hard to shove that all aside to get to the point where I felt able to try to conceive.
Only this morning I was struggling with completely fabricated images of leaving my MIL holding DDs hand while I went to the loo and DD wondering off and falling in a harbour and sinking. Could I jump in and save her in time? Utter nonsense, MIL is late 80s, and scatty as hell, I'd never leave her with DD like that in the first place!
Also pets, images of them being hurt by accident or on purpose. Before DCat passed away I'd panic if he was outside when the bin men came.
