With a 3.1 unweighted, CU will likely be tough. I don’t know how CU weights, but they accept 3.1 and if you’ve had Honors or AP, it’s likely higher (your weighted).
Only a third submitted tests there, but I would - while you’re in the lower range, you’re above their 25th percentile - which starts at 1160.
So let’s call it a reach - but a possible reach - maybe in exploratory studies.
As for Colorado College, very different - you know one class at a time is what they take.
You are definitely TO at CC - not close to the 25th percentile - which is 1380 with 37% submitting.
It looks like they show unweighted GPA - and 6% of enrollees are in your range - so that’s a very high reach school for you.
CU Colorado Springs is a safety for you - so if you like it, it’s a fall back.
I’m not really sure of what you want given you requested the smallest of schools (LACs) but note very large ones too. CUCS is in the middle with 11,000 kids.
I think - CU is a big city itself - in the sense there is so much going on - crowds on campus, kids driving in, parking, etc. So you might really think about that. After all you wrote: t’s the whirlwind of people,cars, noise etc that causes panic. I’ve been in Boulder several times - lots of cars as so many don’t live there but commute in given the costs of Boulder.
If you want to be close, while Wyoming is a different vibe, it’s a thought as was mentioned upthread. CSU would be a better chance for you - although not assured - and it’s large too but not CU large (not good for you I don’t think) and have you thought about UNC or Ft. Lewis. You also mentioned LACs so I noted Augustana and Westminster - but there’s lots of them. A CU is obviously very different than an LAC. Now Augustana is Sioux Falls - so sounds maybe too far. So I get that if it’s too far.
So if asked what did I do in my gap year - I worked in a sandwich shop, learned a lot, and saved money for my future.
Your personal struggles or medical struggles are your business - not theirs - but - you want to stay closer to home, will you have access to your therapist? Or - you might check with each school to see what type of mental health services they provide. You can likely find resources online and follow up from them. I will tell you - they’re likely not great at big publics - at least when you are first there and overwhelmed and the demand for services outstrips the supply of counseling. If you have your home therapist it’s ok but if not, you really might consider smaller schools.
Don’t worry about the school name - worry about your mental health as you continue down this journey.
Best of luck in achieving your goals.
