My family doesn't believe I am ill. My mother passed away a few years ago, and my father remarried. Now whenever my father's wife's family has an event I get pressured to go. The most recent event is a dinner in honor of one of her children. I tried to explain to them that I need to avoid places with plenty of people as I am very sensitive to perfumes, colognes, and other scents. Even so, they still try to pressure to go to events in crowded placse with many people, or that I need to take a crowded bus or train to get to the event. How do I deal with these people? Every time they have an event it becomes a major issue that I can't attend.
