My OCD started when I was 13/14 it stems from having a science lab as my home room in senior school. After seeing a frog being dissected on one of the benches I could never see any of the benches in that room as ‘clean’ after that. It then snowballed to just about everything else. I still won’t/can’t (depending on your point of view) touch door handles with my bare hands and I have special ‘dirty clothes’ to wear when I know I’ve got to sit on a public chair say or I know I’m going to be hugged or touched by someone. One of my lowest times was about five years ago when I had to drive home from my nearest town without stopping, which would have been fine if there wasn’t 9 sets of traffic lights between my 2 destinations! if I did get stopped I would have to go back and start again. Glad that one no longer exists! My OCD comes and goes, I’ve lived with it for over 30 years and I’ve learnt to live with it, I just go with the flow, for the most part it doesn’t bother me anymore.
As boxtops says ‘treatment’ 10 years ago was very different to what is on offer now. Families are encouraged to participate in the recovery process because it affects all the OCD sufferers’ family and friends, you don’t mention whether the fiancé goes with her to see the nurse? I don’t believe she is shifting the ‘blame’ on to you, she trusts you and is seeking your help, she probably realises nothing bad will happen but some negative part of her brain overrides that positive thought. Don’t be afraid to reassure your daughter that touching door handles won’t cause bad things to happen, you reassured her through her childhood it’s just that the reason for the reassurance is slightly different now. Has she been offered CBT (Cognitive Behavioural Therapy)? it works wonders for some. Have you asked if there is a local support group? knowing you’re not the only one often helps, try this site: -

Not all medication is bad; it can just take a while to find the right one for you. I’m no psychologist but you said that your daughter wants to commit and the fiancé doesn’t seem keen, this could be the trigger that released her insecurities about being ‘abandoned’ again. I prompts the question again, is the fiancé taking an active part in your daughters recovery?
I hope that your daughter soon finds her feet again and can get back to a happy and productive life.
