I want to feel sad
Why do you want to feel sad?
I cope with my emotions by feeling sad and showing it -- I really enjoy that.
I understand it, but it's unhealthy to wallow in your own sadness. You should see some professional help about that.
So you're telling me that I should break down and cry to some strangers about my feelings just to make them feel better.
I don't see you your outward display of sadness would make anyone happy. You need to explore what compels you to indulge in this behavior with a  counselor.
