Co-dependents suffer from low self-esteem and make excuses for other people. They are usually women and tend to become the wives of alcoholics, workaholics, manic depressives, plain depressives and passive-aggressives.

Co-dependents exhaust themselves trying to please...

Making excuses for his behaviour or lack of, during consumption of his corpse will not do you any favours. None at all.

As much as possible, switch off the thinking brain and go through the motions. Eat, shit, sleep. Repeat this mantra to yourself when you wake in the morning and when you go to sleep at night.
Eat. Shit. Sleep.
