The stigma thing doesn't concern me at all. I'm not important enough for a stranger to take more than 4-5 seconds to focus on what could possibly be my issue that warrants me seeing a therapist. Then they'll forget all about me and go about their day. If it's someone I know chances are they already know I go to counseling (I'm pretty much bankrupt in the friendship stock market lol) and it wouldn't be unusual.

The waiting room is typically empty by the time I roll up to my appointment, maybe one or two people sitting around but their therapist/whatever retrieves them shortly after I arrive and we don't pay attention to eachother.

I have offered gum to someone once just so he didn't feel awkward with me sitting all up in his grill. Just doing my civic duty.
