Well... I can't really say much about this.

It is true that it can take a while to find the right therapist for you. I haven't had good experiences with therapists myself. In my case, I've always chalked it up to my age. The therapists I've seen were willing to see me because it was their job... or they were in private practice & they wanted the money. But I don't think any of them really thought anything was going to be accomplished. They were just going through the motions.
I've never had a T-shirt like the one you have. But I certainly understand the sentiment. I've sometimes wondered if perhaps other people could
smell my vulnerability.

Or maybe I've just always been oversensitive. I do think that has been the case. Nowadays I just keep to myself. And I no longer see a therapist. So that has resolved my problems. I hope you find some way of resolving your concerns as well.
