Whatever you do don't ignore your symptoms - you can live a happy and productive life if you seek help. I have a niece and a cousin both of whom suffer with OCD. The cousin is recovered, the niece still battling with it. I do not know where abouts in New Zealand that you live but I understand that Middlemore Hospital in Auckland has a great Mental Health unit with a group who specialise in OCD. Give the Mental Health Unit there a call and ask for someone in your area who can help. Believe me there is help out there and you deserve to get it. Good luck for your future and lots of love
