If you aren't happy in this job You may not be happy in another one. There's something else going on right now That's just making you miserable and you might want to deal with it where you are Or you'll have to certainly deal with it somewhere else. If you are leaving I would suggest resign in person when possible Don't send a text give ample notice followed by a written letter. Offer to train your replacement if you have an exit interviewYou can be truthful be honest But be kind and I would just tell you express gratitude on the way out because here's what's going to happen You're going to go.
