Well, it tells me that he made the observation that you don't show emotions, at least around him. Emotions are a normal part of being human, and everybody has them. But it's possible for us to repress them, hold them back, and appear emotionless. And this holding back causes all sorts of psychological problems. The goal for everyone should be to be able to feel emotions and express them appropriately at the right time. I would assume he's trying to help you do this.

As far as mourning the loss of being mentally ill, I'm not sure. I would guess that he means that mental illness is a kind of handicap, just like any physical problem but mental instead. And it's normal for us to be angry about it. How could anyone who, say, lost a leg NOT feel tremendous anger about it? We need to recognize that anger and know that it's valid and normal and nothing to be ashamed of, and then get over it and find a way to live with the disability.

I don't see any type of harassment in what you wrote. Could you explain further?
