I want to echo Sophie_M in expressing how sorry I am to hear that you're going through this. I have grappled with OCD for most of my life, and while my own compulsions and obsessions were slightly different, I absolutely know that horrible feeling you're describing. I wish I could make the feeling go away for you.
At times in my life my OCD has been more or less severe, and the obsessions themselves have changed; so you may find the same happens for you. That said, it doesn't make it any easier for you in your current situation.
It's like the compulsions sort of help quell the obsessive thoughts, but then the compulsions themselves become tedious, frustrating, or even embarrassing. The short answer to your question, then, is no– it is definitely not only you. OCD becomes a problem when it starts to interfere with our actual lives, and it sounds like you're really struggling. Do you think it would be beneficial to talk to a counselor about this? I personally have found success with exposure therapy, but there are lots of potential treatments that you might consider. Always happy to share my own experiences and chat more.
