That sucks, panic attacks are awful! Having spent a whole night in the accident and emergency department of my local hospital myself recently, I sympathise. Glad they did manage to diagnose you in the end, although it took so long, and you're getting treatment.

Yes, being able to lose yourself in something distracting is really good for panic attacks. Glad your crochet is helping. That blanket pattern is really great.

Your unicorn will wait patiently until you can finish it.

Take care and hope you'll be feeling much better soon.
