My mom passed away here 4 weeks ago from the time ...

My mom passed away here 4 weeks ago from the time we found out she had cancer until the time she passed away was only 6 weeks she was only in the facility for 1 1/2 days she was fine going in other than in a lot of pain so she was there to get the pain under control we were supposed to take her home the following morning. It happened extremely fast after we took her there. Since this time trying to deal with the grieving I have done some research and have found that they had my mom on a high dose of methedone and they were also giving her ativan for anxiety and now I see that those two medicines together are lethal. So yes I feel they killed my mom!!
