Drug addiction

I just need to vent . I love my mom dearly but I think I'm about to loose her. She had a back injury about 30 yrs ago and has have several back surgeries and became addicted to pain meds which in turn led to abuse of clonipine, valium, neurotin, tramadol, loratab, sleeping pills and more..I have contacted her dr several times and he had taken her off of her phentanyl patches because he had put her on that to get the loratab out of her hands. She has been to rehab several times..I got to her apt today and she is higher than Mt everest I checked she took 82 tramadol in a 6 day period and 10 sleeping pills tarazapam or something like that in 2 nights and a ton of clonipine. I'm so afraid we will find her dead .I am so helpless because I can't do anything but report it to the drs.and they were closed today
