I have always been overweight even when I was young, not sure if this contributed to my panic attacks or not since my panic attacks started roughly 8 years ago then eased off when I stopped going in lifts, tube etc. Stress last year started them off again. I know being overweight and unfit doesn't help though as if I was fitter I'd be better on the stairs and not get out of breath quite so quickly, getting out of breath makes me anxious in itself.
I have only late last year took the odd Diazepam but nothing else for the anxiety apart from using lavender oil and rescue remedy. I'm now trying Relora.
