Need Guidance

My mom has cancer and became addicted to the opioids because of it. I’ve read online that that is common due to the pain. She was on oxys and got taken off of them after years. Now she’s on tramadol and is addicted to those. I don’t know how to navigate this or what to say to doctors to help her. Due to her pain, her mind is thinking about her medication constantly, and it is so dangerous when she’s home alone. She leaves stoves on, oven on, falls, falls asleep anywhere in any position, etc. Over the years I have done her medication for her but it’s been 7 years and I’m not 26 and so overwhelmed. I am her primary caregiver and have been since the day she got diagnosed and I just feel so incredibly bad that this addiction happened to her when she wasn’t seeking for it - but now I find it hard to take care of my own self because I’m constantly on “mom” mode when I’m not a mother yet! I’m just venting now, but I’m truly just wondering if anyone has any ideas on what route I can take to help my mom.
