WIKitty, you don't have to reveal your diagnosis at all. Your boss already knows you've been off work getting treatment for "something" and probably knows it was related to a breakdown.

All you have to do is say your "doctor" -- you don't have to say psychiatrist -- recommended you ask for reasonable accommodations to continue your treatment by having time off to attend appointments. If you already know how often that will be, you can give your boss a head's up right then by saying you'll have appointments twice a week, or twice a month or whatever it is.

You also don't have to tell your boss what kind of medication you're on. You can say you're taking medication that's been very helpful, and it causes you to be a little different than in than the past, a little slower and more forgetful, but you're feeling better than before and that's what counts.

And hold your head up and smile if you can. You don't have to give more details to your boss than you feel comfortable with, although the people in HR may require you to fill out some forms and get something signed by your psychiatrist. Depends on the company you work for.

I hope it works out well for you.
