OK: do you know anyone who was a nervous wreck, went to the doctor requesting a sedative but was rejected?

A friend of a friend’s husband killed himself in their den. Her daughter and son were on drugs. She was trying to plan her wedding, but was a basket case. So she went to the doctor to get a sedative and was refused. Who are they for? The doctor or his/her family? Do you know of anyone who was turned down when they needed a sedative?
When my father went to a nursing home I had to give the paramedics a bag of all their meds. By the time dad got to the hospital the valium had disappeared.
