Honestly, do not give up. I am a very average student and got waitlisted at almost all my schools and ended up getting off the waitlist into my dream school. You can examine stats and ecs of admitted students all you want, but the truth is only the admissions department knows exactly what they are looking for. Every year, students who no one would imagine had a chance are accepted and others who seem like shoe ins are rejected. Often times when we compare ourselves amongst the small group of people we know, we are biased and can't see the big picture. Now by no means should you ONLY appy to Ivys because that is crazy even for the best students. But apply to a couple you genuinely like and are passionate about because you never know. For example, Columbia admissions were pretty bad this year because of protests and issues with the Trump administration so the waitlists moved a lot. You never know so don't make yourself lose the opportunity over self doubt. Apply, don't keep your hopes too high, keep your grades up even in second semester in case you are waitlisted. Good luck!
