I can't control your thoughts or make you better. That's up to yourself to make those changes. From what I've learnt about OCD, you acquire a very narrow mind. If I'm walking down the street and I pass a man who's minding his own business. I could think about punching him in the face for no reason. I could think of starting an argument with him for little to no reason. Anything out of the norm of what I'd actually do. I could think of grabbing a knife in my cupboard. Anything. If i had these kinds of thoughts, would I get worked up over them? No. Because they are just that. Thoughts. You're living inside your head as though what happens there is a reflection on reality when it is in fact an interpretation and can be taken subjectively.
So if you're on the internet for whatever reason, you think of idk child porn, heroin trade etc. your just interpreting a situation and placing a thought in your head. You're then putting a literal interpretation ON that thought and applying it to reality as if you were associating yourself with looking up such websites. Your anxiety encourages you to apply thoughts to reality as it kicks the fight or flight response which turns you on straight thinking analytic mode.
What is crucial is that you do not apply it to specific situation but on a wider spectrum. So your not just going to be content around these thoughts being dealt with, but that your thought pattern and reaction has changed on a whole.
If you listen to this advice and take it on board you can deal and manage with intrusive thoughts. Seeing as GAD is also a problem, I would also follow whatever your therapist advises along with simply soothing techniques. As you become calmer, over a long period of time, you will adapt to this outlook as far as behavioral reactions go.
Just to reiterate; focus on your life, set goals, hobbies and enjoy life to get rid of too much mental or emotional negativity.
