Stoicism and Loneliness
Epictetus devoted a whole chapter to being alone, and his first move is to pull apart two things we habitually run together.

Loneliness is a hard thing to raise, partly because admitting to it feels like a report on your own likeability. It is also easy to mislabel. People who spend most of the week around colleagues will say they are fine and mean it, and still have the feeling; people who live alone often do not.
Epictetus gave a whole chapter of the Discourses to this, under a title that promises exactly the right thing: What Solitude Is, and What Kind of Person a Solitary Man Is. His opening move is to pull apart two ideas we run together.
"because a man is alone, he is not for that reason also solitary; just as though a man is among numbers, he is not therefore not solitary"
Being by yourself is a fact about the room. Loneliness is something else, and he defines it in a way that is bleaker and more accurate than the usual account: it is a condition of helplessness. What is missing is not company but recourse - someone in whose direction you could turn. That is why he can say the following without contradicting himself:
"it is not the sight of a human creature which removes us from solitude, but the sight of one who is faithful and modest and helpful to us"
This explains the specific modern experience of being lonely in a group chat that never stops. The volume of contact is not the variable.
The resource you can carry
Epictetus's answer is to develop a capacity rather than to acquire people:
"to be able to be sufficient for himself and to be his own companion"
Marcus Aurelius says something similar, and it is worth remembering who was writing. He was an emperor. He was essentially never physically alone, and the passage is unmistakably written by someone tired of everyone:
"For nowhere does a man retreat into more quiet or more privacy than into his own mind"
People go to the coast and the hills, he says, when they could retreat into themselves at any hour they please. Read as a self-sufficiency boast this is insufferable. Read as what it is - a man with no privacy building himself somewhere to stand - it is more sympathetic, and more portable. Note also that he does not recommend staying there. The retreat is brief, and its purpose is to send you back.
Does the Stoic need anyone?
This is the obvious objection, and Seneca opens Letter 9 with it, because Epicurus had thrown it at the Stoics directly: if your wise man is self-sufficient, he does not need friends, and a philosophy with no room for friendship is not one anybody should want. Seneca's reply distinguishes capacity from desire:
"In this sense the wise man is self-sufficient, that he can do without friends, not that he desires to do without them."
And elsewhere in the same letter, more precisely: the wise man is sufficient unto himself for a happy existence, but not for mere existence. He also insists that the direction of the wanting matters. Friendship entered into for what it provides is a contract, and it performs like one:
"He who begins to be your friend because it pays will also cease because it pays."
His test for this is a sentence that anyone who has been through a bad year will find familiar:
"Hence prosperous men are blockaded by troops of friends; but those who have failed stand amid vast loneliness, their friends fleeing from the very crisis which is to test their worth."
Why it gets harder after thirty
There is a line in Letter 9 that explains a great deal about adult friendship without meaning to. Seneca is quoting his teacher Attalus on why new friends are more delightful than old ones:
"It is more pleasant to make than to keep a friend, as it is more pleasant to the artist to paint than to have finished painting."
The pleasure is front-loaded. Making friends is absorbing in the way any work in progress is absorbing; keeping them is maintenance, and maintenance does not feel like anything. Which is roughly why friendships thin out in your thirties without a decision ever being taken. Nothing goes wrong. The absorbing part is simply over, and the part that remains does not announce itself when it is being skipped.
Seneca's prescription for this is quoted from Hecato and is annoyingly unglamorous: If you would be loved, love. There is no technique attached. It is a statement about which end of the exchange you have to move first, and it is the only actionable thing in the chapter.
What the Stoics have nothing to say about
Worth stating plainly, since a lot of loneliness now runs through dating: there is no Stoic material on this. The corpus contains no advice on choosing a partner, nothing on courtship, nothing about the particular modern grind of meeting strangers through an app. Musonius Rufus writes on marriage, and it is genuinely interesting - he treats it as a partnership of two people who look after each other completely, which was not the standard Roman view - but it starts after the choosing and it comes with a good deal of first-century prescription attached.
So what is on offer is narrower than the problem: a distinction between being alone and being unsupported, a decent explanation of why the number of people around you is not the variable, a warning about friendships that are really arrangements, and the instruction to go first. That is not a cure for a lonely decade. It is more than most philosophies manage.
