Not sure if it was an anxiety or panic attack?

When I was younger 8-12 and sometimes even now. I would suddenly get very dizzy and get this weird feeling that I can't explain. My mind would start racing but not in the thinking about a lot kind of way in the in feeling like every thought is going a million miles a minute and I can't concentrate. I would break out in a cold sweat and I can't concentrate on anything. I had to force myself to think about getting to my bed or I would start freaking out. After I laid down for about 10 minutes I would be fine.

These would just come out of no where, I have never told anyone about them and I don't get them that much anymore but sometimes I still get that sickening feeling if I am going somewhere new (I am shy)

I have no clue whatsoever what these attacks were.

Anybody have any ideas?
