Don't feel it is necessary to have them understand what you went through.
Because they can't!
Most people see JWs as just another small, "harmless" religious group and the only things they know about them is they (used to) wake them up on Saturday mornings, they don't believe in Jesus (all that D2D ministry and people are still confused) based on the fact they do not celebrate Christmas, and then some who read the news may be aware of the prohibition on blood transfusions, though more likely, they know of a JW who died refusing one. More than likely many of them think JWs refuse all medical care (confusing them with Christian Scientists).
