Being Alone vs. Loneliness: Are They the Same Thing?

Humans experience loneliness.
Humans also experience being alone.

They are not the same—though they are often confused, especially when we’re trying to make sense of our emotional experiences.

Being alone is an objective state. It occurs when we are not in the physical presence of another person.

Loneliness, on the other hand, is an emotional experience. It often arises after a period of feeling unseen, unacknowledged, or disconnected from meaningful and supportive relationships.

Loneliness can be triggered in many different ways. Maybe you’re the last person in your friend group to be in a relationship. Maybe you were the first to get into your dream college—and instead of feeling celebrated, you feel oddly isolated in it. Loneliness doesn’t have to be the result of something going wrong. It’s simply a feeling that exists within the complexity of being human.

Being alone, meanwhile, is something many of us crave at different points in life. We may want to be alone after a long workday. We may need solitude to focus, to rest, or to process something painful like a breakup. Alone time, in itself, is not pathological—it’s often necessary.

Where these two experiences begin to intertwine is through a psychological concept known as solitude tolerance.

Loneliness or periods of being alone tend to become problematic when someone struggles to tolerate them. This is not a weakness—and this isn’t a self-improvement lecture. Solitude tolerance develops through the ability to self-soothe, sit with uncomfortable emotions, maintain a stable sense of identity, nurture secure attachment, and remain present with one’s internal experience.

Being alone can actually support nervous system regulation. The problem is that many people never get to the other side of this benefit because discomfort arises first—and feels intolerable. It’s not being alone that’s harmful; it’s the inability to sit with oneself when the noise quiets.

Clinically speaking, loneliness becomes concerning when it begins to impair daily functioning. Prolonged loneliness has been linked to increased rates of depression and anxiety, reinforcing the truth that humans are not meant to do life in isolation. Unlike being alone, loneliness can occur even when surrounded by others. You can be part of a large friend group or a committed relationship and still feel lonely if your relational needs go unmet.

Loneliness is also associated with increased stress hormones, sleep disturbances, impaired immune functioning, and long-term cardiovascular risk. These outcomes are not personal failures—they are signals.

Often, the issue isn’t being alone, but what arises while being alone. Clinical contributors to fear of aloneness include attachment insecurity, reliance on external validation for emotional regulation, difficulty tolerating unstructured emotions, and avoidance-based coping patterns.

In a world where connection is constantly at our fingertips, we paradoxically have less tolerance for the discomfort that comes with being alone. This fear can keep people in the wrong relationships, the wrong dynamics, or the wrong company—simply to avoid sitting with themselves.

The goal isn’t isolation. The hope is to be able to be alone without it spiraling into loneliness or self-destruction. There is risk in choosing solitude, but there is also growth.

This is where therapy becomes meaningful. In the therapeutic space, people can build emotional attunement, increase discomfort tolerance, strengthen secure emotional regulation, and challenge the limiting belief that being alone must equal loneliness.

My belief is that if more people could move past the idea that being alone automatically means being lonely, they might finally meet the person they’ve been avoiding the most: themselves.

I write this with deep conviction—because I’ve had to learn it too.
