Burn the letters from the person who told you that apologizing is the only way to make people stay, because some people would leave even if you told them you were sorry for existing.
You built a home miles away from the ocean. It’s not your fault that you drowned. It couldn’t have been your fault.
With the right person, you could sail the ocean in a boat which has a hole at its bottom, and still not sink.
The right person would stay even if you didn’t thank them for doing so.
So, dear you, when you’re done breathing the water out of your lungs, lick the salt off your lips, and be on the lookout from your light house.
Dear you, never apologize for being yourself.
