I'll start off with one, Being upset about a breakup that happened hundreds of years ago.
One of my books features an immortal protagonist and I've as such thought about this quite a bit. More than the answers already provided here, what I found interesting as a writer was the balance I needed to find between making an immortal detached from mortal values while still being engaging to mortal readers.
Said as a pithy question, if you can outlive everyone's decisions and mistakes, what would it take to make you do anything at all?
Having to keep track of that evil snail.

Being eaten by sea anemones, tuna, sharks, swordfish, sea turtles, penguins, and other jellyfish.

The amount of shitting and wiping I d imagine you’d have to do, hemorrhoids would likely be unbearable overtime
That old person feeling of no longer being with "it", and what's "it" now being strange and scary probably compounds over the centuries.
Given a long enough time frame, the vast majority of an immortal life would be spent buried beneath something or floating in the void of space. Think about it, you outlast planets and stars. When those go dark, but you don't die...nothing to do but float in space.
You might counter that with, "well yeah, but eventually I'd find other sentient life forms and/or people again.” And sure, maybe, but that wouldn't last as long as you...and then you're just alone floating in space again, for the vast majority of your life. The only thing to look forward to, since you will outlast everything, is the end of time itself.
I think there is a clear difference between being immortal and being indestructible. I would think if your planet breaks apart you'd probably die with it being crushed or whatever. Also always unclear if being immortal means you don't need to breathe air.
I wonder if it might engender an advanced sort of solipsism and callousness towards other people. After thousands of years of the world coming and going around you while you remain, would you even recognize other people as real or meaningful?
Having to constantly find new hiding places for the blood chalice, and keeping up with all the latest scanning methods so you can develop countermeasures. Your secret is never truly safe.
Knowing the answer to some of history's biggest mysteries, because you were there, but being unable to speak about them because, 1, that would expose you, 2, nobody would believe you either way because nobody expects you to be THAT old.
Also, it is already frustrating seeing kids being dismissive or denying events that you yourself have lived. Imagine being thousands of years old and seeing so much shit, but those events are rarely retold, forgotten, or straight up denied by conspiracies or future governments that won't admit their fault on it.

IDK, I feel like researching for supporting evidence of a theory you already know is correct would be much easier than researching to try to piece together a theory from no information. I think you could put the truth out there as credible and well-regarded theories, even if there are incorrect alternative theories that people also have to consider.
On a long enough timeframe, even the strongest-willed will want to die eventually
Just depression in general. I don't want to live one lifetime, let alone never being able to die.
If you're immortal in a body that isn't broken then that might be a different story, but you'd still grow to love people only to have to lose them and go through that pain over and over.
Being asked your birthdate in order to view a game on Steam, and the year dropdown not going back far enough.
I once entered an extremely far back yet technically plausible birthday there and steam just wouldn't accept it. I remember thinking "what if Kane Tanaka wanted to check out this steam game, you just wouldn't let her?" (RIP by the way, she was the last oldest person whose name I learned. They change too often)
Depends on the type of immorality. Do you continue to age? If no, what age do you stop? Eventually the universe will die. So what happens to you then?
It might be fun for a while. Maybe even a long while. But that fun will be gone in an instant compared to the trillions and trillions of years you will float in a dark dying universe of nothing.
