It always felt to me that this post nuclear war sounds like choosing to be tortured until you die vs just dying on the spot.
We are talking about full on nuclear annihilation.
Its not 40-50 years of suffering, it sounds like generations of suffering, early struggles not to starve to death (if you are not a remote farmer or remote isolated community with farmers - tough luck scavenging vs hordes of other survivors).
Soon if you managed to be part of community that managed so far, you will be faced with other communities. Fighting over resources or farmland, resources are scares human lives are not. Eventually everything will fall under tyrannical local warlords, who will be constantly fighting too.
Daily fighting for resources, no medications or people who can heal you. Stupid cuts can become lethal, huge number of birthing deaths as c-section is quite common (google says 31.8%) so on and on
The lone survivor rebuilding nation is a romantic view, but I think realistically staying alive will be a grim premise that I'd rather skip.
Would you still be ok going through above scenario?
