One day I was working out fine, exercising great
The next day I went to the gym and as soon as I sat down on the bench 10 seconds later I felt this emerge wave of heat dizzy and anxiety hit me really hard and I felt like I was going to just pass out right then and there I was shaking and so I got up and left thinking something was wrong. 
And ever since then two weeks ago I felt a little bit of vertigo every day I felt just completely off and every time I go to the gym I just felt uneasy and even sitting down at the barber I felt another wave of what I felt before hit me and then yesterday I went to the gym and was working out and near the end of my workout I felt the wave of it hit me again and I had to leave early I couldn't even go to the grocery store because I felt like I was going to pass out just to wave of chest pain dizziness felt hot anxiety and just like I was going to follow over and pass out.

I'll feel little episodes here and there that last 20 seconds at most.

But would that be GAD or something anxiety related?
I thought anxiety doesn't last that long? This is going on two weeks.
But I felt fine the day before this all started.

I do have an appointment with the cardiologist on Thursday to rule out any angina or heart problems. Fingers crossed.
