Is this normal after a panic attack?

I had my first sober panic attack this morning and it's stopped 13 hours ago but now I feel horrible pressure in my head and can't stop worrying and feeling stressed. I don't know what to do :(

That's how I feel after a panic attack. It last for a while. But eventually after not panicking for a day, you start to feel relief.
