"Next Spring" = end of March to end of June. This year. But yeah, I guess that's too complex to grasp (or "next Spring after this one" was too hard to say) and it probably really was supposed to mean next year.
If I struggled to the end of my determination, to the end of my way of life with my followers, if the result is ruin, then this ruin is inevitable. Grieve. Shed tears. But you cannot regret.
