I think @dorisirene has an excellent suggestion regarding transportation.
Have you considered or previously asked your current Medical Oncologist about any trials etc that may be available to you elsewhere? How long have you been working with your current Medical Oncologist? Do you know what the estimated time is (on average) that one might start to determine as to whether your current treatment regime is working or not?
Or have you inquired about it? Perhaps your new Medical Oncologist can reach out to Princess Margaret to see if they are aware of any treatments available to you there. By doing it through your current Medical Oncologist perhaps it would or may reduce many visits to another facility for treatment options and you may be able to have them all working together.
Are you currently working with a Palliative Care doctor or asked about a referral to one?
Have you reached out to someone who can help you with your feelings of being "worn down" and "blocked" (like a social worker)?
This process is very difficult emotionally, mentally and physically and that all has an impact on both yourself and your family. Reaching out to any resources available to you to address those feelings may help as well as letting your team know about these feelings so that perhaps a medication might help with that. It is my knowledge that Palliative Care doctors can consult only, consult/watch/advise or take over treatment entirely. It may be something to consider.
I hope this may help you and give you some things to consider and wish you well no matter your decision and on your unique journey.
