I’ll start off with one, Being upset about a breakup that happened hundreds of years ago.
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.
Does your consciousness evolve to Godhood, and you reach back beyond time and create the universe which birthed you?
being alive
That old person feeling of no longer being with “it”, and what’s “it” now being strange and scary probably compounds over the centuries.
Without getting into the heat death of the universe and all that, I can think of something that happens much, much sooner. I’m only middle aged and I already don’t like where the world is going. Can you imagine being centuries, or eons past the era you identified with? Can you imagine how insufferable young people and old people alike would seem when you have centuries worth of life experience and wisdom? Can you imagine a horde of little edge lords on the internet confidently yet incorrectly telling you about the signing of the Declaration of Independence, when you were there when it was signed?
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.
I would assume that over centuries or eons, you’d amass enough wealth and power to comfortably circumvent those sorts of things. If you’re not running the world after living for 2000 years, then you’re a ley-who-say-her.
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.
Getting imprisoned for thousands of years unable to get out.
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?
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.
Read this on the largest number every used in a mathematical proof.
Then ask yourself, if you think you could handle this number in microseconds let alone an eternity
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.
Presumably you will advance along with humanity though, or failing that, just figure out the transcendence thing yourself with so much time?
I don’t think anyone would choose to stay ‘meatbag human’ for trillions of years.
Either humanity gradually grows to despise you for your ancient morals
or they don’t ever meaningfully surpass where we’re at today.
Based on your question, you might dig the book “Boat of a Million Years.” The author put quite a bit of thought into just that.
The eventual heat death of the universe would be painful
But would you survive?
