after-panic attack comedown

i recently was in the hospital for a panic attack (didn't realize that's what it was) when i took a thc/cbd gummy. it was only 10mg, but my heart rate got up to 160+, and they had me on ativan to calm me down before sending me home. 

i'm almost mad about it all because it's been years since my last panic attack, and this one has wiped me plain out. my chest is achy from the tachycardia, the strain, and shaking/near convulsing i was doing, and i feel there's this disconnect between my body and mind. it makes sense the body would be traumatized by the whole thing, at least from the panic attack, and would need to time to recover, but i feel i can't convince myself that i'm fine, now. 

i feel calm. but every time i go to sleep, be it an hour or 6, i wake up with a sudden racing heart, and it takes ages to get it to go down. when it happened yesterday night, it triggered a minor anxiety attack that took about an hour to calm down from. today, i'm so exhausted from getting shit sleep that when i woke up and my heart started going, i was nearly unaffected and did what i could to get my heart to go down. it only took about ten minutes, which i was glad for, but it sucks to be in full control of your emotions whilst your body is freaking the fuck out. 

i'm working from home this week because i get winded walking around, but sitting, i'm fine. last night's shower was the definition of a nightmare; i can manage my heart rate some, but suddenly i'll feel like fainting and what is that??? i want to enjoy calming activities, but my body is on high alert for nothing.

i'm just so tired of this shit and want to go back to normal. i want to SLEEP
