Write me a resignation letter
Make sure to include that it's because I found another job and to "thank" my employer for the opportunity they gave me
To whom it may concern:
After much consideration, I've decided to end it. I'm sincerely grateful for what you have done for me, but I'm afraid I cannot continue this life, so I must go. Don't try to stop me, I'll be happier this way.
Goodbye
why do you need a letter?
just tell your boss
