I would never recommend someone continue with an activity they dreaded no matter how good they were at it. So he doesn’t get an athletic scholarship to Amherst. Big whoop. There are hundreds of fine colleges out there and plenty of other ways to get merit dollars if you need them. BTW, my kid ended up as a Naval officer without doing any athletics in high school. He got involved in Krav Maga when he was in college and when he need to prepare for the Officer Candidate School physical readiness test he made sure he was in shape to do so.
My son quit cross country after sophomore year because he wanted to focus on theatre and was not enjoying cross country. He transfered that work ethic to theatre, got a huge lead role junior year that changed the trajectory of his life, and became president of the school’s theatre society. Dropping cross country did not hurt him at all in college admissions, and no interviewer ever asked him about it. Colleges want to see your passions.
The nice thing about those sports is they are objectively time-based. So regardless of your assessment of your skill, it is quite easy to see where you rank in the state, and country in your events. Boys usually improve a bit as they age, girls often do not. But you would have a pretty good sense now for how your times compare to the times at the colleges you like, and whether there is any realistic hope of running in college. Your coach already knows that.
My niece was a national class middle distance runner in high school but had a complete monster of a coach. They ran all over the country and were really good, but she loathed the whole thing by senior year. She hasn’t run a step since the end of that season.
My DD is a sophomore and just went through the agony of quitting track. She was pretty good and the team was counting on her for this spring, but in the end that didn’t matter enough to overcome the miserable time she had last season. She was on a high school varsity team as an eighth grader at her previous school and knew what a great season felt like, but was not getting that at her current school (coaching, teammates, any of it) so she pulled the plug. She has another sport she’s good at so she’ll still be active, but running was no longer bringing her joy, so she sent it away.
Anyway, as long as you’re moving towards something better it’ll be OK if you leave one activity behind. If you force yourself to continue you may feel a similar pressure to continue in college (“it’s the only reason they let me in”) and be even more miserable through a longer season for even more years. Blech. Be true to yourself, and if you find you miss it then go out for the team as a senior. Track people are pretty cool and will certainly take you back. 
I’d encourage you to stop running and replace it with something else you enjoy. To be competitive at the Varsity level simply takes too much time doing stuff you hate. You will resent it and that will undermine your training and your performance in races. . High school mountain biking has exploded in most of the country and would be a fairly easy transition - most compete at the club level and it’s a lot more laid back than your typical varsity sport. It is also growing at the collegiate level. Its worth a look.
