First, I applaud you loudly (hear it???) for giving this a shot. I can only guess how difficult it must be. And now, let me say this. I think you have to decide which is more important to you: trying to keep working with these kids or taking care of your own health and sanity. You alone have to make that choice, and . whichever it is, don’t let anyone else second-guess you. Also, keep this in mind: this is a decision that is not irreversible. If you take some time to nurture yourself, there may come a day when you’re ready to return to teaching.
