A very important element of self-care and survival for teachers is talking with other teachers (or former teachers) and being honest about feelings of frustration , failure etc. Knowing you are not alone is helpful.
Also, seeking ways to relieve stress and take care of yourself. Do things to accomplish more than just survive your days but take breaks from the stress of the job. Take time to do whatever makes you relaxed and happy (differs for every person). Try reading, exercising, yoga, taking a walk, crafting, or whatever makes you happy and removes you from thinking about the stresses of your job.
