Hi spindly,
Have you talked to your doctor about anxiety? I have had panic attacks for years, and know how debilitating they are, but with meds and CBT the panic attacks have been under control (for the most part).
I find that deep breathing exercises help, along with self-soothing, meditation, hot baths and distractions. I can give you more info on these if you're interested (send a PM). These definitely help my anxiety personally.
So sorry you've been feeling this way.
