I'm glad I could help in a small way. The two most important things for you to keep in mind are that:
Thoughts aren't reality
The OCD is not you. It's like a virus. It lives in your mind and it feeds off your anxiety. So what it does is it constantly searches for thoughts and triggers that it can explode and make you miserable. But none of it is real. And it's not that you're going crazy or whatever, it's that all your thoughts get filtered through the OCD, so it gets to choose how you experience them, how you interpret them. I knew a woman who was absolutely convinced she was going to go crazy and poison her baby. The thought of her losing control and doing it made her sick and miserable. Now, of course she would NEVER do it, it was her OCD making her think that it was a possibility, which fueled her anxiety and made her miserable, which made the OCD fat and happy. The only treatment is to learn to starve the OCD, which is possible, and meds and therapy help. And let me make it absolutely clear, you WILL starve it out. It will get small and weak and you'll be able to laugh at it in a few months. It won't ever fully go away because no human can ever fully get rid of anxiety and regret and fear, but once you learn to recognize a thought as an OCD thought, it's much easier to dismiss. For me, OCD thoughts actually make my head feel different, like it's burning a little. I stare off into space and get lost in an anxious thought as though I were having a really powerful daydream. But I shake my head and say, "That's just an OCD thought," and I try my best to ignore it. It works, sometimes better than others, but it does work.
I also carry around my little plastic lizard. When I first met my pdoc I described my OCD as a sleeping dragon that roars to life when it senses a tiny bit of anxiety. He said that we're going to take that dragon, and make him a little lizard. I mentioned this to my mother in law and she sent me the little lizard that's pictured in my avatar. My pdoc loved it and said that whenever I have an OCD thought, I should take out the lizard, set him on my desk and say, sarcastically, "Really? This is what you want me to think about? Really?!" It seems silly, but that's the point. Don't treat your OCD with any respect. Make fun of it. Attack it with silliness. Find a stupid little thing that can act as your OCD and carry it with you and be silly with it. Make it a joke. Eventually it'll be a joke.
OCD is a long road that goes up and down. It's muddy, and slippery, and sometimes you think you've reached the end only to find out two weeks later that you have more climbing to do. Try not to get too discouraged. Remember what Christopher Robin said to Pooh, "You are braver than you believe, stronger than you seem, and smarter than you think."
And also, you're not alone. Ever.
