welcome ACH.
i don't think you are in a " death spiral"...(doom and gloom are not helpful)
i think you did a smart thing by reaching out here and connecting...better than running for a drink.
work stress is awful...i was in a terrible circumstance myself that went on over 18 months...it will pass and you can think outside the box about career options too. a drink will not erase the stress, just mask the problem and make you feel worse.
