I finally get a job doing what I've trained to do and my mind is racing, I feel like I can't catch my breath, I'm practically clawing at the walls

Feel like a fool

I know I'm not, I purposely took this job as a final test, I had to know, but still

I know what it's like to be nervous and I know what it's like to be anxious and nervous doesn't have me going outside like once an hour just so I can feel like I can breathe
