I am 34, but when I was 21 I was in an abusive relationship and traveling long distance to see my SO.

I remember I was on the highway driving to my SO and I got a hot flash (I am man) and I felt my brain was on fire. My heart rate jumped to 120/130. I started crying and I turned around and drove home. 

When I drove home it felt like someone else was driving home, not me. For about a year, I felt like I was a shell of a person and I was watching myself. 

I always thought it was a neurologic disorder. They scanned me for seizures, tumors, till one day I was told to speak to a psychiatrist for anxiety. 

I never did. 

One day I started keto and went to the gym, and lost 100 pounds a year later, which is what got me out of my depersonalization rut. Oh and breaking up my with my SO. 

Anyways, on this rainy day, I can't help but think, can anxiety cause this? I believe I have anxiety to some degree. More so health anxiety. Back then it was anxiety about my SO + Health. 

Thanks!
