N* basically everyday

So a lil backstory. I’ve had emet my WHOLE life (im 20 now) and on Boxing Day I had a bit of a cold/flu thing my partner had given me. I went to drop some things off at his work (he’s a security guard) and when I got to the shop to grab said things I started feeling SOOOO n* in my throat like I could gag and tu. I managed to get his things and get to his work where it only got worse. I felt a ball in my throat and literally felt like I was going to be s but my stomach felt fine. Just throat n* but REALLY intense

Ever since then anytime I’ve been in a car (me driving im almost always fine but I’ve never gotten car sickness before so i highly doubt it’s that?) or I’ve been at work I’ve gotten really n* and had the same feelings, sweating, heart racing, mouth gets REALLY dry and feels like im gonna gag/tu* (mainly in a car),feeling like I could tu* but I never do. I’ve been taking ondansetron when it’s been really bad. It got so bad the Saturday before new years I had to leave for work but I’ve never done that before in my 3.5 years working there.

Does anyone know what this is? Is my anxiety getting worse? It’s never been like this before and I just want it to stop.. I’ve had the odd occasion where it’s happened and I’ve not been at work or in a car. Like at his house the other week or at my own randomly on a night. Any advice is GREATLY appreciated because this is ruining my life.. I used to love to go out and do things, random trips to the shops, etc but now I’m terrified too incase this happens while out.. thank you guys 🥹🫶
