So much jargon for life-ails common to everyday man! Smh! That in itself, could cause a panic attack. Research shows there's a theory for nearly every day of the year.
First off, I am very sad for your cat's problem. Have you researched natural healing treatments for such things? I don't know why; but, dabbing a little cotton ball with apple-cider vinegar might offer relief.
DON'T QUOTE ME ON THIS...I AM NOT A VET!...:+)
May I suggest deep-breathing and centered focus that GOD IS IN CONTROL...and THERE'S NOTHING TOO HARD FOR HIM.
Have you considered yoga? YouTube has several vids for beginners.
Have you considered a go-fund-me for your vet fees? I know people tend to be very generous with pets needing care. If you create a page make sure you do a post with Steemit so the community can help as possible.
Take care...I pray you'll accept things as they come.
Peace.
