I have never posted on anything like this before but I just wanted to say I have exactly the same fears as you. That me and my daughters will get threadworms and never get rid of them. I think about it day and night and it is ruining my life. I had a course of CBT but it didn't help. I am goingback to my GP next week as I feel unbearable. Sorry im not being helpful in the slightest but I just wanted to say hello and I hope you are ok. I don't know anyone with this specific fear. The therapist told me he didn'tknow how to help me as he'd never heard of it eirher. Reading your posts has made me feel a glimmer of hope.
