On Etanercept, Cymbalta For Rheumatoid Arthritis, Fibromyalgia, Disc Disease. Depression, Given Ativan. Right Dosage ?

I am petite female, 112 lbs. on etanercept, lyrica, cymbalta, methotrexate, vicodin & sometimes oxycontin for severe rheumatoid arthritis, fibromyalgia, degenerative disc disease, osteoarthritis and osteoporosis. I have had some depression (but I bounce back due to Faith!) and was recently given (by a dr other than my long-term physcian who was out of the country but whose office was never contacted) 4mg of Ativan when I went to a local clinic to ask about how to refill my r.a. meds. I was crying--but due to having an $800 bill for this med. that needed to be paid prior to my being able to order my next shipment. I've had several dr's/nurses tell me this much of this drug w/o contacting my personal physcian was too much for my body size? Is that correct? What amt would be correct for future knowledge?
