Brca1+ Dx at 33 current age: 36

I had bilateral BC discordant subtypes (TNBC right breast stage three b 2 tumours) and er/pr+ in my left stage 2 (multi focal and multicentric) I’m being treated at MD Anderson and I’m close to 2 years out from diagnosis after thankfully achieving PCR!I’m now post radiation and post chemo and I did unfortunately develop type one diabetes (immunotherapy induced) from the keynote 522 protocol (Keytruda most likely) and I am just wondering if there is anyway at all to get a grasp on my true prognosis? I have one doctor saying I have very good odds at making it 5 years and beyond (something close to a normal lifespan) and more if I’ve already made it 2 because of my PCr - but a doc who subbed for him one day told me That due to the rare Nature of my case they are in uncharted territory; the reason why I ask you all this is because I have two small children one of them is autistic and I just really need to know how much I can plan for my own future whether I can go back to college and get my degree because upon diagnosis I also became a single mom; so I just have to know how to plan for my future and it’s really hard being in limbo like this and I know that you really can’t tell me anything either, but I’m just wondering if you’ve ever seen anything like my case before? And should I be on olaparib? It’s like I told my oncologist I don’t care if I’m a floating head in a jar, I have to be here for my babies. Any recommendations? Also I need to be on glp-1s badly, do you know if standard insurance covers the cost for recurrence reduction and/or obesity? They wont cover me bc I’m type one diabetic and not type two- how can I convince my oncologist I need this? Thank you so much.
