I only got IP because I got a baby from my husband during my first squadron tour. I’m told the IP who really made the choice was an O3 IP (F14 Tomcat Pilot who has sent a bird into the drink) He took me out of the POCR board pile after I timed out. I’m sure you can lateral if you gut it out and prove in your fitreps that you took your one and only chance and dared to be great!@Pags mentioned their first fun flight was their solo, and I'd echo that. Being beat up in early contacts because you suck, sucks. It gets better. Way better. Can't speak too much on the airsickness bit, just that for most people it does get better. If you haven't yet, before you DOR, TALK TO YOUR CLASS ADVISOR!
I will say that if you DOR your chances of getting anything like IP are about zero. If you med attrite, or airsickness attrite, and sometimes if you normal attrite, you often have a wide spectrum of options. Highly recommend you continue, keep trying, at the very least complete primary before making a decision like this. There are a lot of people that aviation isn't for, but I bet there are more that regret dropping too early. I don't know a single winged aviator that wishes they had DOR'd when things got tough in training.
