I've had people say things like "just get over it" to me.

The "just" part serves to minimize what "it" might be. This typically comes from people who either don't get it, or who don't truly care. And those who don't care might not even like you.

As an example of someone who doesn't get it, my own mother would often describe my bouts with depression as "a funk," and she would tell me to just get over it. I told her it doesn't work that way. She still doesn't get it, and never will.

As for someone who doesn't care, or who might not even like me, I had a boss say something that was upsetting. I sent an email to my team letting them know that my grandfather had died, so "please be understanding if I am not as enthusiastic as usual."

A few hours later, the boss called me in for a "chat" with the team's other leader. He starts off with, "We've noticed that you're not as enthusiastic as usual. Would you like to talk about it?"

I start to tell him that my grandfather had died, and that I can't afford to go back home for the funeral, so I'm just going to keep working. But before I can finish, he interrupts and says, "We recommend that you just get over it, if you want to keep your job."

There are people who care out there. Most of the world does not. In all fairness, I have come to not care about most of the world, either.

Don't worry about disappointing people like this. They started out disappointed, and might very well have their own issues that they're hiding. I write them off.

Be concerned about disappointing yourself. There is more than likely something you can do to fix that. Then you'll no longer be disappointing yourself.

Those people don't matter to me, and they shouldn't matter to you.

You should matter to you. I should matter to me, and I've been working on it.

I hope it works out.
