Afraid that it is NOT panic, but an emergency?

I've been suffering from panic attacks for many years, and no matter how bad they felt, I always knew it was just the feeling. I always thought I was dying, but I knew deep down it was just the panic attack or its symptoms.
But there was this one situation when I thought it was a panic attack (similar symptoms etc.), but it was a serious case.

Since then, not only has my panic disorder gotten worse, but I can no longer distinguish whether it is a “medical emergency” or “just” panic.

That is to say, before I could clearly say: “This is panic”, but now I no longer dare to judge it that way and I panic even more.
