As a (so far) survivor/refugee of the inexorably tanking non-profit sector, you have my heartfelt sympathy and best wishes. It os draery hard to leave a job that you love and have made such a personal investment in. My advice, for what it's worth: don't beat yourself up for ranting and railing a bit, you deserve to vent...take what comes next as it comes, but be sure to look after yourself.

Hugs,
