It took a while for me to tell people I was in therapy. I found it very hard. My husband knew right from the start. Later on I told my friends and siblings. Eventually I had to tell my coworkers too, when I had to take a step back at work.

I can imagine you feel vulnerable, since you don't know your coworkers that long. But being in therapy is nothing to be ashamed of. My experience is that everybody is very understanding.
