A panic attack feels like you're dying. Which is a phrase used so often people don't realise the terror of actually feeling like you're dying while losing your mind.
That said, your unchecked anxiety could develop into a panic attack.
"In the depth of winter, I finally learned that within me there lay an invincible summer."
- Albert Camus
"Everyone wants to get out of the rain
Wants to be free, wants to see no more pain
We're guaranteed that the season will change
'Till then, I'm keeping sunshine on my brain"
- Mike "Eyedea" Larsen (RIP)
