I have been on both sides of the fence.<p>I had continuous allergy problems without knowing it for a large part of my life. Among the effects were a minor depression.<p>When I got rid of the allergies I had a bit of an identity conflict, I wasn&#x27;t the one I thought. My humour and world view weren&#x27;t as dark, I liked people more. It is a strange to adjust your self image so much after 40.
