Well, it could be she was misdiagnosed or she doesn't have a "severe" case or she has learned to compensate and be involved with family and work. Every individual handles BP differently, depending on personality and environmental influences, for instance.

Unless you know a person really well, best to not make assumptions. Many who suffer a variety of things, not just BP, appear rather normal, with rather normal lives, with or without meds. We humans can adapt rather strikingly most times.

Sometimes you can't tell from the outside looking in. There are many cases of drunks that are seen to be the best people in the world, and only those close know the truth.

Just because a chap is holding a newspaper doesn't mean they can read. Many have ways to hide/cope with what haunts them.
