Sorry for your pain Violet.
I think these substances we take hoping to ease the anxiety and sleep issues make them worse over time.
My anxiety attacks about 15 yrs. ago during a very tumultuous time in life, and they prescribed Valium. Geez, I said to myself this is an addictive substance they prescribed-SOME SOLUTION! I might as well drink--at least if lifted my up while it calmed me down. Every time I went off alcohol the anxiety would become overwhelming, as would the sleeplessness. Sleeplessness leads to paranoia for me after 4 hrs. in two nights, plus all that tired, useless ruminating lying in bed for hours-ugh?
I hope you find peace
