Relationship FOMO

hey guys, I have been having some relationship FOMO. I have tried dating and have been with people, but not for very long. I have hooked up etc., but for some reason I just feel like I’m going in circles. I date someone, then we stop, on to the next one, sometimes hooking up in between, etc... I’m kind of in a lull right now because I have some health stuff going on that I think needs more of my focus, but I dont know what it is I just feel so alone. Any advice for coping with relationship FOMO?
