@YourRubyMaker I completely empathise with the panic attacks. I had around eight months worth of them many years ago after a period of great stress (although nothing as bad as what you are going through AT ALL).
I found the following things helped:
Recognising that they are panic attacks and the sensations WILL pass
Not fighting them. If I felt my heart start to race, I told myself okay - you are going to start feeling hot and nauseous in a moment and 'other worldy' - like you are watching the scene from within a dream... You have felt this before and you know it will stop. Just go with it.
And once I accepted they were happening, rationalised what they were and acknowledged that it will end when it ends, I would focus on the sensations that I was feeling in an objective way. "Oh, I feel this" and "now I feel that". By being clinical in my thoughts, it took the panic element away a bit.
Slow breathing
Keeping busy even when they were happening. Distract yourself and go about tasks - especially ones you have to concentrate on.
Drinking a sugary drink
Telling your DH what's happening. "I'm okay, but I'm having a panic attack and feel strange, just so you know..."
And above all, tell yourself that there is a completely logical reason for what's happening. You are going through the most stressful time of your life. It's understandable and it WILL stop.
Of course, i can't help with the labrythitis, but if the panic attacks are happening on top of that, i hope this might help
