First thanks to anyone who take the time to read this and respond, I really value it! 

The individual mentioned in this post is aware that I'm seeking this advice.

So I am in a position where I have a close relationship with someone diagnosed with BPD. 
The person with BPD has really been struggling for a long while, I have known them for 3 years. Suicidal ideation has been present throughout this time and feels like an ongoing concern. 
The individual with BPD has been involved with the system ( foster care support services etc) throughout their  life and seems very traumatized by the lack of control ( completely valid) they don't believe going to the hospital will help them, they have done it many times and who am I to say what will work if they have in fact tried this before? 

The individual invited me to be at their doctors appointment next week and we have been talking what we need to advocate for. The individual wants help but essentially just seems so exhausted from trying and nothing feeling like it's working to change the intensity of what they are experiencing. 

The exhaustion also seems to be impacting their ability to explain what they want/need right now, I am concerned that the individuals who work with them, doctors included take this as apathy? This time last year the individuals was engaged with the same clinic and they discharged them because they basically said the meds should be enough and they couldn't really help with the rest. The individual re-engaged with the clinic and is seeing a different doctor.

But I  don't know what Ishould be helping to advocate for? 

I feel greatly alarmed when I realize they have been experiencing SI for three years with no real intervention ( other then me constantly checking in and trying to remind the individual that there could be more help out there) 

Does any one have any ideas of what we should be asking for? 
It feels like we need to approach the doctor with the solution or ideas or we will just get the same response of trying the medication. The individual takes the medications for like a month and then stops for like a week and then usually tried to start again and the doctors just say they have to get compliant on the meds before anything will change. But it feels like because the individuals already just feels so bad that staying compliant on the meds is really difficult and we are just in this same cycle over and over. 

This individual is low income and mostly relays on community programs which seem really hit or miss and generally short term. 

I feel concerned for this person and want to make sure we are asking for things that may help? 

I'm nervous for this appointment with the doctor as I am scared they won't have anything to say past take the medications or go be in the hospital.
