I really do believe that there is help out there with pain management for everyone. Some combination of medication, therapy, and distraction, that will make it possible to construct a meaningful life.
It may not be the life you had or the life you wanted, but it will be a life you wouldn't have wanted to miss out on.
I am on more medication than I would have thought possible but I am functioning. I can concentrate, play strategy games, read, do what needlework my hands allow, cook, take care of my family. Not the way I used to, my house is a mess, some days I cannot stand at the stove or food shop, there are no extras. It is still more than if I weren't here.
The difference between this and lying on the sofa with an ice block and a heating pad is my PCP's willingness to handle pain management when my neurologist gave up.
For me the combination of MS Contin (morphine) and Gabapentin has worked well. BuTrans patches work well for others. There are so many things out there, and sometimes it takes a combination of meds to get relief. Something will help you. It won't always be like this.
