I Needed to Learn
I have two friends that suffer this condition.
When I made friends with the first she didn't let on about her condition though I knew something was not right so I did some research. I had a talk with her mother who confirmed it was BD.
I've some very scary moments with her in the past as a result of not being careful with her medication. She is much better now. Her B/F of just over 12 months has also learnt of the danger signs.
My other friend is OK with it now.
