I did. One time, back in my 20's, I applied for a job at a coffee store (not like Starbuck's, but mostly sold coffee you make yourself at home), and, thinking I was being "open and honest," I told the employer about my OCD and panic disorder. He asked wouldn't it make it difficult to work, and I told him I would be fine, and he didn't say anything (but his tone said it all) but, to this day, I'm pretty sure that's why I didn't get the job.
