[Serious] Feeling Dizzy and Scared, Need Help

Experiencing Dizziness and Lightheadedness - Need Help!

I have severe anxiety and its starting to create physical symptoms. But my anxiety is triggered by health concerns so when I get anxious and start feeling tingly or lightheaded or sick it freaks me out even more and it just keeps going in this circle for hours straight, sometimes days. I could really use some help or reassurance

So I don’t understand what’s going on.. last Feb I had taken a med for 2 days and woke up with extreme shakiness feeling disoriented and then all at once my hands started to tingle i felt like I was going to pass out and got extreme burning and tingling starting at the back of my head and then through my whole body. Since then i’ve been paranoid about a stroke and has caused extreme paranoia and panic attacks because I still have weird tingling and burning. Today I got this extreme sense of impending doom and I was doing fine and then all of a sudden I felt super heavy my bf and I were almost home and I felt like I was going to pass out (so I started panicking) and then my hands started tingling and I couldn’t feel my hands or my face and arm. I went to the er they took vitals and I sat there for 5 hours and that all eventually went away. I opted to go home but still feel odd and like brain foggish. Anyone else ever have this or know what it could be? Because no i’m really paranoid and panicked
