The side effects you experienced are unfortunate; if it happened to me, I would be very angry. However, the stigma around mental health is real and prevents many people from getting the help that they need. You can be angry without contributing to the stigma.
Actually, I found that the psychiatrists I saw universally did not listen to me, and one even told me to live with injustice (!!). I feel that the stigma is caused by the medical profession.
