The right to die with dignity?

Do chronically ill patients has the right to legally end their own life? My heart and mind always split into two directions when this question is posed to me. 2 years ago I woke up screaming out of my sleep from unspeakable pain in my left knee and hip. I’d screamed with the slightest movements. Orthopedic doctors cancel my appointment before I could even see them, because there was nothing they could do surgically for my leg. Some doctors had the audacity to say that because I was unable to walk my pain wasn’t a high priority compared to someone who could walk. There was a point during that time where I just wanted Jesus to come and take me from my misery. My knee and hip made a weird popping sound and I feel better, but I still have pain from time to time. What do you do when doctors and physical therapist don’t want to work with you because you are non-ambulatory? What if there’s no cure ? To be honest I’ve had this pain throughout my life because of surgeries of the past. This last time was the worst, I didn’t think I was going to survive it. That pain seeped into my brain and change my Outlook on my life. A big part of me says that only God has the right to end life. The other part of me says I am a hypocritical jackass for judging somebody for not wanting to live through unspeakable agonizing pain.
