I always do. I had a therapist once that didn't understand why I had to leave work after an attack. Even if I went to the bathroom and waited it out I was just exhausted after. All I could do is leave and go home and sleep the rest of the day.

I haven't heard of feeling tired, I didnt

I usually continue to experience moderate anxiety after a panic attack, so definitely not tired. The anxiety has the opposite effect.
Doesn't a panic attack sometimes cause a surge of adrenaline though? If so, it would make sense that you would feel tired after.

I feel completely worn out after an attack.

I feel completely physically drained after a bad panic attack. Sometimes even the next day. It depends on the severity and length of my panic attack.

HI. Exhaustion is very common after an anxiety/panic attack. When we start to panic there is a rush of adrenalin that shoots through our bodies. The body does this because of the fight or flight response. When in 'danger', even perceived danger, the body gets ready to fight or run. In either case we need the adrenalin to help us do this.

Think of it this way. If you were in a jungle and a tiger came charging at you, you would run to save your life. After, you would be exhausted from all that running and fear and adrenalin rush. This would be considered "normal" after such a dangerous encounter. It's no different when we have panic attacks which is why it is very important for us to rest after we have one. The body needs to recover from all the perceived danger and adrenalin rush.

I hope this helps.

Yes when you have a bad one and its long it totally drains all the energy out of you. When the attack is over try to do breathing exercises and dont get down try to pick yourself up and carry on i know its hard but its good for body mind soul. Take care, Lisa
