Unless you need to disclose this personal info to arrange an accommodation, do not bring it up. When I've let supervisors know I had a psych diagnosis, it absolutely did me no good at all . . . and did me unnecessary harm.

It's better to ask for help to deal with a specific need. Like: "I tend to get apprehensive in a new work environment because I really hold myself to a high standard of job performance. It's hard to reach that standard when I need more experience to get up to speed." That's way better than, "I'm prone to panic attacks that make me unable to cope."

Never think that by disclosing a disability you are increasing the chances that you will be shown extra compassion by supervisors and co-workers. Work sites are competitive environments. There are usually at least some who think they make themselves look better, when someone else looks worse. These types look for vulnerabilities in you that they can disparage. Workplace gossip tends to be rather ruthless.
