Hi OP
I haven’t had time to read the other replies on this thread so sorry if I am repeating things. I just read your post and found it heart breaking as I can relate to it so closely.
I recently got diagnosed with OCD in adulthood. I’m early thirties. However, I now recognise that I had it most of my life and that a lot of my distress and anxiety as a young child was linked to OCD. Unlike you, my parents were sadly not informed about OCD and it wasn’t recognised as such until recently through a private psychiatric assessment.
Over the years, I had tried everything to manage my brain / associated anxiety including CBT, mindfulness, meditation, exercise, diet, journaling, cold water therapy, breathwork etc. I felt I was ‘keeping a lid on it’ but in reality the thoughts in my head were never really changed.
I started 50mg of Sertraline in May 2024. It has changed my life. I empathise so much with your daughter’s distress over the thoughts always being in her head. I had no idea how exhausted I was until they stopped. I could have wept with relief at having a quieter mind. It was as if my thoughts had halved. I no longer have such distressing, intrusive thoughts. My compulsions are far more manageable. It has been such a drastic change that I feel I am a new person.
I don’t know how you feel about medication or whether this has been discussed. I know there is the additional aspect of her age to consider. However, the way I view it is this: if I was physically ill, I wouldn’t hesitate to take medicine to feel better. It has taken me time to accept it but I do now.
(Just to say, the first 4 weeks on Sertraline were very difficult with increased anxiety - this is normal. However things then improved almost overnight).
Wishing you all the best OP. Your daughter sounds wonderful and you are a lovely Mum.
