Wow, well described! "Black Hole". Gets the point across nicely. I think I may have encountered people like that in my life. Yeah, it's sorta like sympathy-seeking behaviour. They want you to pity them and whenever you bring up a problem, they'll try to one up you, as you mentioned.
I think the key difference between the typical idea of a narcissist we have and these people is how they go about their self-absorbed ways - one praises themselves where not required and the other pities themselves where not required. But I guess they both unite in the similarity of attention-seeking.
I think I have caught myself being this way a little bit though. 🙈 Yeah, I agree it's not right and you should allow other people to grieve and rant. Everything doesn't have to be about you. I do try to correct myself though.
Thanks for sharing this article. Good reminder. :)
