Severe Anxiety and Panic Attacks After a Car Accident

Hey. I’m very confused and don’t know what’s been going on. Around six months ago, I was doing very well in my life. A car accident happened and I was pretty okay. I stopped taking birth control and then boom. One day in class I had such a bad panic attack I had to leave school. And then it happened the next day as well. And at work. I ended up going to the mental hospital and ever since then, I’ve had severe anxiety, panic attacks, dizziness, vertigo, and much more. I thought ptsd but I never was really thinking about the accident when my anxiety was bad. Now my vision is strained and it’s hard for me to drive and go in stores. I don’t know what to do. I don’t know what it is. I’ve tried medications and therapy. I’ve tried vitamins and exercise. I’ve tried it all. When will this end? Whatever this is. Could it be due to my birth control? Is it something physical? Plz help
