My entire life it seems like I have been prone to anxiety and/or depression from my youth till now. I worked a very high stress job for 8 1/2 years in the retail industry. And one year I started to notice that I would have these "attacks". The symptoms are labored breathing, dizziness, nausea, and what I interprit to be loss of muscular strength and at times control. I find here lately when I have them that they span out over multiple days. When I am having these they happen anywhere from 2-4 times a day for the span of 3-4 days. I thought originaly they were anxiety attacks. Just the result of a hard life and emotional distress. But I find that I have these even when I am not under any immediate or pending stress, pressure, or anxiety. Sometimes while watching TV with my family they just arise. Yesterday while on the treadmill at my local gym one hit and completely disoriented me. What are these?View Thread
