hello Casper, welcome to the BB site where OCD seems to be a very dominant issue at the moment, whether it's the time of the year being Xmas, or the fear of seeing relations at this time so these could be contributing to your OCD.
Any medication needs to be reviewed by your doctor on a constant basis, because what happens is that our body gets used to taking the same medication after a long time which can then make it ineffective.
There is no doubt that the effects from having this illness are very strong, something that only people with this illness really understand, because for others to take on board what it does to us only seems to be ridiculous, but we know that it's actually what happens to us.
I say 'us' because I've had OCD for 56 years and what ever anyone has said about what it does to us is so very true, because all of it has happened for me, and still does even though I take a SSRI medication and have for over 20 years when I was diagnosed by my doctor.
We develop a routine when we are home because sometimes that's when it has the strongest power over us, such as touching something as many times as you need to, like before you go to bed you may have to look at something 4 or 5 times, whatever number it is for you, and if you don't then your anxiety goes through the roof, in other words it has to be done everytime.
It doesn't matter what ever feeling you have, either being with your heart, intrusive thoughts or checking the lock, they are all the same and all are so powerful, perhaps you should go back to your doctor and ask to try another SSRI, because everyone has degrees as to how extensive their OCD is, but even by having a very low OCD illness still controls our life. Geoff.
