Same here. One of my eternally compassionate yet so far anonymous co-workers who probably noticed I'd been self-injuring about a year ago, forged my name to create an email account at live.com (hotmail), then used that email account to order "helpful" literature on drug abuse and mental illness, sent to my office in a most particularly NOT plain unmarked envelope, so I'm sure all kinds of people got to see it on its way to my desk. And then followed up about six months later with a catalog for pornography and sex toys. When I asked my manager what was going to happen, he told me I was being inconsiderate of my co-workers who were understandably afraid of someone with an apparent mental illness.

I went to my doc and got her to do an ADA accommodation request that allowed me to work from home (I have the kind of job where this is perfectly feasible). That was great for a few months, but suddenly my manager decided he'd rather have me back in the office.

The manager is a real piece of work. In his small group, so far there's been (at least) one nervous breakdown (me), three people sent to anger management, numerous writeups and grievances with HR about harassment among co-workers and this manager, and yesterday he topped it off by giving one of our group a public reaming-out in email for a trivial procedural thing, which left her crying for two hours, and me fuming all day then going to the ER this morning with chest pains that turned out (fortunately) to be "just" severe heartburn/gastritis.

As well as having to take lots of nice antidepressants, tranks and sleeping pills just to function, I take strong meds for GERD because of esophageal strictures and hiaitial hernia, so the stress is taking its toll on me physically as well as mentally. I'm off to my regular MD this afternoon to see if I need another gastroscopy to see what's going on, and maybe surgery to repair the hernia and reflux because it looks like the Prilosec/Prevacid/whatever purple stuff has stopped working.

Yeah, do the day by day thing, keep things professional (I slipped up a time or two and got written up), and don't let yourself get pushed around. Research your options, especially if there are accommodations that will help you cope with your current illness, for example a quiet, undisturbed place to work, maybe work from home part of the week if that's feasible, a scheduled time during each work day for interruptions then they leave you alone to get your work done without distractions, and so on.
