I was gonna say, CBT might work for you.
You are so not alone. I have OCD and it holds me back from everything to the point where I can't even start because I am so obsessed with picking the 'right' thing that I can't even get started. I don't have the impression that people are making fun of me or trying to harm me (to the extent you are describing) but I do have extremely disturbing and disgusting and intrusive thoughts almost constantly, not to mention counting, categorizing, and making shapes out of things. I can't focus on anything longer than a few seconds and I am constantly agitated.
I understand your desire to start out with a clean slate. However, I would caution you that if you just drop everything and move you're still not addressing the issue. If it's within you, you're just taking it with you. I would recommend seeking help for it and learning how to manage it before you attempt the other stuff. Not saying you can't make changes until you get 'well' (who the hell even knows what that means), but just that making life changes in and of themselves likely won't cure what it is that you're describing. I would talk to somebody about this: a doctor, therapist, psychiatrist, someone.
