I think my workouts are causing my Panic Attacks

I didn't get to finish my session just now because I had another panic attack that came from exerting physical effort. I noticed this happens when I do high intensity (today's push day) and since I felt really great when I woke up, I thought it was a great day to do high intensity. Then boom, sudden dizziness, arms are numb, slight chest tightness, and uneasiness crept in.

I had one like 2 weeks ago with the same trigger (and also a push day and high intensity too!) and it's frustrating because I can't finish my workouts.

It's very frustrating. A year ago I was living my life normally.
