Hey Dan,
I think I speak for most applicants when I say most of us had that fear. While West Point may appear to be the solution to those aspirations, and it is, however that vision can be attained a thousand different ways. I too was tunnel visioned on USMA when I had first applied, and after being rejected I was crushed. I moved on to ROTC while reapplying for the academy. It wasn't what I had dreamed of since I was a kid, but I ended up having a great time and met a lot of incredible people.
I ended up getting offered an appointment this time around for the class of 2027, but regardless of that fact, I am genuinely happy that I got rejected that first time. It taught me a hard lesson that will save me a lot of disappointment and pain in the future. I don't see it as a "waste of a year", as I developed in new ways and enjoyed many new experiences which would've been impossible at the academy. I instead see it as getting to experience the best of both worlds, the fun of college, and the honor of going to West Point.
The point I'm trying to make is to not getting tunnel visioned things happening exactly to your timeline. If things are meant to happen a certain way, they will. Even if it takes a bit longer. If it wasn't meant to happen, you will find the replacement to be just as or more gratifying then what you envisioned.
Best of luck to you on your path.
