You give yourself some grace. Mourn, get angry, smash your crystal swoosh and meaningless "awards". The stages of grief will come and go.....let them, dont fight it. Tr to eat right, exercise and spend time with friends. There's an external group called 6453 Alumni - some members are cool-aid drinkers and Swoosh tattoo owners, others are hardened veterans. Talk to everyone you can and be open to change. The grief and angst will pass, the anger won't. Seek counseling if you're up for it....I don't know anyone who hasn't benefitted from it.
Be kind to yourself. Change is difficult at best, even when you're in charge.
There is life, and jobs, outside the berm.
There are more of you/us than are left continuing their awful management practices within the berm.
