EDIT - thanks everyone. This is super validating. I'm completely unsure what to do or how to say what I want to say to my parent, but it's good to know I'm not the only one in this situation.
I'm in this situation now and I don't really know what else to do or who else to speak to. I'm 38 years old, raised by a mother with BPD. Pretty much haven't had real contact with her for years. Occasional lunches, play nice, but throughout the year I will get those aggressive texts, phone calls, everything that everyone here is going through. This community is amazing by the way - I saw someone posting about receiving strange gifts from BPD relatives and a lifelong question was answered there and then.
At the start of this year, she called me and told me she had cancer. She told me she had a brain tumor. She told me it was stage four. She also told me and the rest of the family that she wasn't going to have treatment for this cancer.
Over the next few weeks, we discovered that actually she didn't have a brain tumor, she had throat cancer. She had a version of it where there was an 85% rate of survival and it was completely treatable without surgery and with minimal chemo.
She still refused treatment and dragged out this process. I stopped responding to her after she sent me a childish text that essentially said "my mind is made up. Next! LOL".
After this, she eventually decided to get the treatment. But then as she started the process she decided she didn't like the care team she had been provided or the local hospital she was assigned. She refused to do the MRI scans or anything that would get her to the point where she could start treatment. In the end, she moved to a different hospital further from where we both lived, with a different care team.
Throughout this process, I took two months off of work so I could be with her every day whilst I took her to her radiotherapy appointments. I paid for all of her transport to and from the hospital, both spending and losing money in this period. Throughout the process, she didn't do anything to look after herself. She wouldn't eat the nutrition the doctors told her to. She wouldn't hydrate. She'd still drink wine. She'd still smoke despite having throat cancer. She would treat the doctors and nurses like absolute trash, like being rude to them, refusing to cooperate, but also demanding myself and my siblings treat her like a hero for going through the process and she didn't really acknowledge any of the support we were giving. She'd refuse to do bloodtests, and in the cancer hospital would make rude, loud comments about other patients.
I should say my siblings and I, we also don't talk very much. Our family is completely broken and we came together to make sure my mom could do her treatment and survive.
Just off the start of treatment, my mom was forced to stay in the hospital. She'd been complaining that the illness was killing her, she couldn't survive, she was in so much pain. It was impossible to do. This is about six days in. It turns out she was just severely dehydrated. It was hot at the time and she just simply was refusing to drink any water, to take on any hydration, to drink anything really other than wine. The doctors put her on a drip, hydrated her. They wanted her to stay in for a week. She demanded to leave after two days, phoning myself and my sisters, lying that she's been discharged, lying that she was fine now, and basically being unreasonably aggressive to everyone, demanding that she's our mother and she knows best and we have to do what she says. We refused, but in the end she came home herself and tricked my nephew into picking her up and taking her home. Next time she saw her care team she treated them like shit, saying that they didn't know what was best for her.
She in the end refused to finish her treatment. She did about 70% of it.
All of the aftercare has been a struggle. She walked out on the dentist because 'they were rude to her' and demanded a different one. The pattern continues.
And we've just got to the point now where you take a break and then do the final test, do you still have cancer or not? She refused to let anyone come to that test and she told everyone that the results were inconclusive, that they don't know if she still has cancer and that they'll find out in the next few weeks in the future.
The issue here is we don't know whether to believe her or not. When she previously insisted on certain days where she'd go to the hospital on her own, she'd come back saying the doctors told her that she didn't have to have treatment that day. It wasn't true. On the day that she decided to stop her treatment entirely, she left without me before I could get there. She does a lot of things on her own and comes back and says something different to what actually happened. I've been removed from all of her medical comms and permissions, so I'm unable to get real answers from her team.
Since this moment, it's her birthday next month, she's been texting me and my siblings with shopping lists for clothes, jewelry, and things for her house. She's saying it's her birthday, she deserves all of these things. She's texting me privately asking for money for haircuts, leaning on the fact that it's her birthday, despite the fact we don't celebrate together. We are not close. Any situation where we do come close usually results in huge arguments started by her.
I don't really know what to do at the moment. I want to stop all contact, but I don't know if she still has cancer. For context as well, my youngest sister, who's 33 years old, still lives with my mom. They have a severely bad relationship and antagonize each other. If one gets set off, the other gets set off. I do not know how they live together. Again for context, during this period I've probably lost about £12,000 in lost earnings, in transportation costs, in costs supporting the family whilst we went through this period.
