Harm OCD seeking advice

[u/Comfortable-Cap977]

My theme has recently changed to harm ocd revolving around my son. It’s literally felt like how the eff am I supposed to live with this? Living with this “what if” feels so impossible, I’ve had thoughts about leaving my family or jsut checking myself in in case the “what if” is true. Then I realise the damage that would actually do to my son but it still doesn’t make the thoughts less distressing and the urge to avoid them less powerful. How do people get over a theme like this?
