OCD and bad anxiety. How to cope with them both?

I suffer from OCD and anxiety. The only time my anxiety starts in is when I am not on schedule. Say I am supposed to meet someone for dinner on a Thursday night @7 pm. And they do not cancel. I get anxiety and get thrown off my schedule. Because well I will admit I cannot help it.

I want to be able to stop worrying and stop the anxiety and move on in life. But it’s hard to.

So if you have OCD/ Anxiety how do you cope with this?
