I was feeling miserable.at a previous company. Lots of oncall. Poor choices in engineering. Lack of management support. I asked a friend on how to deal with this? He told me to check-in on my mood a week later if it doesn't change quit. I quit after a week. BEST decision, half the team evaporated in six months. I took six months off cleared my head, joined a better place. Your health is number 1 that's it.
