Working as a Survivor - No fear or No way?

I had a category 3 brain tumor removed nearly 6 six years ago, radiation, chemo the usual protocol. On my 5 year survival anniversary I started applying for senior engineering and project/program management positions and I got one! I was so excited. It was like all of my hard work and perseverance was worth something. I quickly noticed that I was still very capable but had difficulty dealing with the new COVID work environment. People worked from home and to be honest the office environment added no value for the individual employee. Networks, IT support, and even leadership - voice of the employee meetings virtual from over seas. It was a huge transition and although my problems were no more or less stressful than to others, I seemed to take it much harder. People would ask me why I would stress over things so much. Why would I work more than 40 hours to get something done. No one else did. Didn't I know the 80/20 rule. Quiet quitting, I guess. It doesn't make sense to a girl forever loyal to her country and war fighters. So, I got burned out. I started to have small seizure looking episodes and then more major episodes. I was ashamed even though I brought significant value. I quit my dream job and worse it was due to my own arrogance. The next part will sound very familiar, I'm sure. Since I had a very recent clear MRI, brain cancer related concerns were ruled out. EEG showed no epeleptic activity. I'm quite use to medical "practice" and "protocols" but I'm not sure I want to spend a good portion of the rest of my life working at finding a cause that will likely lead to prescription drugs that will make me sleep all day. I am a Carpe Diem Girl. Are there any companies worth working for anymore or should I find a less expensive and simple life.
