How to hold a job with anxiety?

I was diagnosed with an anxiety disorder when I was 16. It wasn’t too bad, it was bearable. I was able to work. My first job I had until I was 19. My dad died when I was 19 and ever since that (it’s been almost 2 years) I’ve experienced frequent panic attacks and have not been able to hold a job. They’re so scary. I have went to my dr because I thought I was having heart problems. I was having chest pressure, heart rate was VERY high, lightheaded, dizzy, nauseous. Everything was fine and it was a panic attack. I have them daily, for literally no reason. I’m so tired of living this way. Please someone tell me what I can do to make them stop 😞 It’s ruining my life. My husband is thankfully amazing and he has a great paying job so I’ve been able to not work but I just want to again. I’m in college and about to go to nursing school I have no idea how I’m going to get through like this.
