Panic attack?

All of a sudden, I felt an overwhelming heaviness all over my body, like I was going to faint. Then my heart started racing, and I started shivering. My mom said I felt a little hot, and my breathing was uneven. I felt really dizzy, and I was about to scream because I thought I was dying. I feel a little better now, but I still feel heavy in the head and pretty tired. Was that a panic attack, or something else?

It could well be anxiety. They are all symptoms of anxiety and panic attacks. I think you should see you Dr and get a check up and take it from there. You are feeling better and are safe so try to stay calm and relax. Good luck

Sounds like a panic attack. Did something happen to trigger it or was it random? This used to happen to me a lot. I would break down in tears afterwards and sleep it off. Had no idea I had anxiety until years later I realized what it was. If this is happening a lot you should see a therapist or talk to a close friend.
