To Old?

I have taken 10mg for 7 years. Last script denied by insurance received letter today saying I’m too old. I take and go to bed. I don’t take to get high, I take to sleep. I’ve had some bad shit happen. My mind races at nite. The letter says denied because I’m old and never tried doxepin or remeleton. WTF, Now I’m old, can’t sleep and pissed off.
