Ugh...I'd can't say I know how you feel but I can understand why you are feeling down, out, drained, and madder than hell. There's nothing I can say that will change your environment so I remind you of the Serenity Prayer to maybe help with your emotional self..."God, grant me the serenity to accept the things I cannot change, Courage to change the things I can, And wisdom to know the difference." You have been placed in that position based on the compassion and experience you bring with you and for that, thanks be to God. Stand up straight and keep marching forward for good and the safety of your students and staff - regardless of whether you'd rather just rip their head off and spit into the hole. Best wishes and good luck! You can and you will!
