So within the last few months I've been experiencing really intense anxiety that is mostly triggered by fears related to my health. I'm a generally healthy person in my 20s and I have no reason to have this fear, but it's probably because my anxiety symptoms are mostly physical (heart palptatioms, shallow breathing, etc) and it makes me think I have a medical issue.

These last couple of weeks I've started to randomly feel woozy or lightheaded. Usually it doesnt last very long, maybe a few minutes, but these last few days it's been lasting for a long time, like hours. When I feel it I try to eat something sugary in case it's just my blood sugar being low but nothing changes. So now I just have this constant fear that I'm gonna pass out or that something is seriously wrong with me. Whenever I feel this way it sends me into a panic attack. It's been happening when I'm at work too which stresses me out even more.

 I just got my annual bloodwork done, so tomorrow I have an appointment with my doctor to see if anything abnormal popped up, but until then I'm feeling extremely anxious and woozy. I know lightheadedness is a common symptom of anxiety, so maybe that's what I'm experiencing, and if that's the case for me I'd really appreciate some advice on how to deal with it when I start to feel this way. What works for you?
