What are my Chances of getting into CU Boulder

I am a senior at a college prep high school in colorado. CU boulder is my top choice school to go to college, CSU is my next choice. I am worried I won’t make it into either school. My freshman year, I had decent grades and then sophomore and junior year came and my GPA plummeted. I got diagnosed with epilepsy my sophomore year, and had brain surgery, that is what I wrote about in special circumstances essay for my applications.
My ACT score was a 22.
Overall unweighted GPA is a 2.54
Ive played two sports each year in high school, and am involved in the club DECA.
What are my chances of getting in?

I got in to CSU with a 22 ACT and a 3.29 GPA. Im also OOS though… I had good grades and then really struggled my junior year because even though I took hard classes all of high school, I took extremely difficult classes my junior year. I got in with a rough (2.6) junior year and no compelling story (regarding a reason for my grades anyway). I think you’ll be ok at CSU but CU may be a different story. If you’re applying to A&S it might be fine. Unfortunately you’ll get very little money, but good luck!!
