hoping sumone can relate

So for the past couple of months I've been experiencing a very scary feeling.... First occurrence....I was talking to an admissions counselor and noticed that as she was talking I started getting this feeling of not getting enuff air...I start feeling hot and a lil light headed and once I went to stand up I could barely carry my self..I felt so heavy to the point I had to lean against a wall to hold myself up and if I hadn't done that I would've fell out or fainted...I don't think this is anxiety but clearly nuthin I experience feels like anxiety so I'm unsure at this point...has anyone experienced this? It happens maybe once a week or once every other week...not too often but it is definitely scary when it does happen...happened to me yesterday too while at home...luckily I was near my bed so I was able to lay down....why is this happening...am I having mild strokes or sum thing? Please help

sounds something like being bilious or vertigo. straight to the doc. feel better soon.
