Lovergirls and Loverboys, i need yalls take on this

So a little back story on myself. Im a guy, loyal asf, never cheated or talked to two girls at the same time and currently single. Also something else about me, I get nauseous extremely quick almost everyday at stuff like normal food. So im a loverboy and what i mean by that is that when i find a girl attractive and she shows the tiniest little bit of interest in me, i go all the way. So when i talk to a girl like message and stuff like that I get nauseous because of nervousness and anxiety. Im very introverted btw. This nausea thing has been happening since beginning of high school when dating became well what it is today. And i also make the girl my world like my life revolves around her world and any tiny thing makes me nauseous like if she takes too long to respond, if she goes on tiktok lives (i have trauma on that from the past), if she hides small stuff from me. So i wanted to know if this is like normal? or like is there something i can do? because like moving closer to being in a relationship makes me nauseous like every message to and from the girl makes me nauseous because of anxiousness. So its really making me wonder if I'll ever be fit to be in a relationship again if this happens all the time.
