Thanks for all the feedback everyone.
Maybe I am feeling down just cuz I've gotten to know Pat. LOL.

Silly Pat.
Sandy, I'm taking escitalopram. It's marketed under the name Cipralex in Canada and the U.K. and Lexapro in the U.S. So the package mine comes in has the brand name Cipralex on it. I've just been referring to it as Lexapro on PC because most people are familiar with that name.
I know what you mean about getting a rush from a new job and then coming back down to reality. I talked to one of my colleagues and my boss this afternoon and both of them were saying what a hellish week it has been. (We're dealing with the volunteer committee from hell. They're totally out of control.) My boss actually said to me, "I feel like I'm having a breakdown." So, maybe it's not me and maybe it's not my medication. Maybe it's just situational. We're so busy at work right now. It was comforting to know that I'm not the only one feeling frustrated and confused and overwhelmed. I had been thinking it was just me -- not being able to handle the pressure. So it was comforting to find out that my colleagues are feeling the same way.
I had also been -- at the same time as being run ragged at the office and then bringing work home in the evenings -- putting a whole lot of pressure on myself to get my flat cleaned up -- and failing -- so that was bringing me down. I think I was just expecting too much of myself this week.
I had to work until 9:30 tonight and I was supposed to go to my boss's housewarming party tonight after we finished at the university, but I just decided I needed to acknowledge my limits. I announced at 9:15 that I wasn't up for a party. I decided I needed to come home, take a bubble bath, relax and get a good night's sleep. I'm worn out and all "peopled out." I've had a bad cold for almost two weeks, haven't been sleeping well, haven't been eating well, etc. I think I just need some "me" time. I have a date tomorrow night, so I'm hoping a good night's sleep and having that to look forward to will cheer me up a bit.
If I'm still feeling down next week, I'll go talk to my doc about it.
Thanks again everyone for listening to me ramble. I'm not good at keeping it brief.
