Annoying coworkers

So one thing that's really been annoying lately is my coworkers.

I'm trying not to talk about or think about my divorce/break up anymore at work and just focus on the job. But people will randomly say "oh youll find better she was just a lesson." Or something like "she was send to make you stronger."

For one I don't want any lessons and two i don't want to talk about her or it anymore like please give me a break I feel bad enough it's been since March.

And no I don't want to try again. Give me a break. I dont want lessons I don't want to be stronger and I dont want to think of her.
