You're welcome here, GJ. Come and read and post in
obsessive-compulsive/ ? There are lots of people there with similar stories. And talking to people with similar stuff going on can be powerful. You don't need a diagnosis or anything.
obsessive-compulsive/topic103176.html is a good place to start reading. It explains about the checking and anxiety. And gives some options for working on this. It takes time but things can get better.
We don't use blogs very much for conversation.

Because it's very hard to remember where you've posted [except in your own blog.] So mostly we do chat in the forums. Maybe post there what you've said above? And reply to other people too. That's a good way to get to know people. And start to build up support.
