Oh, CMC seems like a terrific fit - I can see why they picked you; and hopefully you will experience that good fit as well. You don’t have to worry about the “what if my LAC is too small?” question, because the consortium overall is just as big as the universities you listed. I feel like you will really like the “vibe” at CMC; and the opportunities there are fantastic. They have a great DC program, too, which was a priority for you as I recall.
Looking at your original list… okay, you didn’t end up at one of your super-reaches, but that’s how it goes for most people. This outcome is, in my opinion, much better than anything you had in mind for matches or safeties - both academically and financially.
If you don’t mind my saying so, you have a tendency to jump to negative conclusions about your opportunities (for example, the Boy’s State experience that you almost bailed out on but that then turned out well). This would be a really good time to practice not going into a new situation with one foot out the door. There are far more amazing opportunities at the 5C’s than you could possibly avail yourself of in four short years. Don’t waste any of it second-guessing. So many students would (figuratively) kill to be in your shoes. Keep looking forward and make the most of it.
(Also, I know convenience isn’t the most important thing, but there are even nonstops between SLC and Ontario, CA, which is 15 minutes from campus.)
