I'm so sorry you are still struggling. It was very ****** of your friend to leave you hanging.
Are you in Therapy or did you just go to the doctor for medication? (I still love that you yelled at the receptionist!)
Remember the meds can take several weeks to kick in.
Today did sound rough for you, but I'm glad you got out into the fresh air. If you had stayed in bed you would have gotten rest, but you would have deprived yourself of the possible opportunities, and you would've beaten yourself up wondering..

about the what ifs?
As far as the bathroom attendant goes... don't give it a second thought! Women crying in the bathroom is the definitely the norm.

I don't know a single woman who hasn't cried in the bathroom! Let's be honest... we go in there to fix make-up,
cry, get away from boring dates, gossip with girlfriends, and SOMETIMES use the toilet.
Not that you asked for an opinion and I hate to say it but someone should...
As far as your ex goes... I think you dodged a bullet! Think about it... marriage isn't a fairy tale. It's supposed to be
forever, through thick and thin, health and illness... and he couldn't handle an episode of depression!? What would've happened if (God forbid) your children got sick, one of lost your job or house? If he doesn't have the nads to stick by you when there are available treatment options and positive results in sight.... he doesn't seem like the type to stick.

...Which, of course, does NOT mean anything to you, because you are heartbroken, and are probably, still love him. But when you get to the anger stage of the greiving process.. remember...
You can do so much better!

I think you deserve a man who is unwaivering in his loyalty and love to you. A real man would've stood by you, and held you up when you couldn't stand on your own. You shouldn't settle for less!
Once again, I'm sorry for adding my two cents when it wasn't requested. Please, ignore me if I have offended, but keep posting!!

I really hope you feel better soon.
