You're not joking. You're just being an even bigger ass, but now instead of jokes, you're feigning concern. It's stupid.
There's subtle motivations behind everything. A genuine apology comes without insulting the other party. Clearly you didn't do that here, and clearly you and everyone else knows what a genuine apology should NOT look like: "go get help with your mental problems, I'm really sorry."
It shows just what kind of person you are. It's not me who's disturbing... it's you, the person behind a mask.
Also clearly my words are from a place of anger and seriousness not mental issues. Mental problems are a very grave issue and it's a far bigger problem and the symptoms are far more extreme then what's happening here. But you know this. And you're trying to falsely re-frame the situation by disgustingly using mental issues as some kind of tool to discredit the other party. It's just vile.
I don't wish you the best of luck. I think someone like you doesn't deserve it.
