What codependency actually is
Codependency is a popular term, not a clinical diagnosis. It started in addiction-recovery circles to describe partners who organized their whole lives around a person who was struggling, and it has since broadened to name a wider relationship pattern. At its core, codependency is when someone’s sense of worth gets wrapped up in caretaking, fixing, or being needed, to the point that their own needs fade into the background.
The pattern is usually two-sided. One person tends to over-give and over-function, while the other leans on that support, and the arrangement quietly reinforces itself. The caretaker feels valuable when needed, which makes it hard to step back even when the dynamic stops being healthy. That blurring of where one person ends and the other begins is the heart of the term.
What codependency can feel like
It often feels like love taken to an exhausting extreme. People describe feeling responsible for everyone else’s moods, unable to say no, and anxious when someone is upset with them. Their own preferences can get so faint that they genuinely don’t know what they want apart from the relationship.
There’s frequently guilt attached to self-care, as if tending to your own needs is selfish. Saying no can feel dangerous, and being needed can feel like the main source of self-worth. Over time this is draining, and resentment can build underneath the helpfulness, even though the giving is sincere.
What codependency isn’t
Codependency isn’t the same as being caring, generous, or committed to the people you love. Healthy relationships involve plenty of mutual support and sacrifice. The difference is balance and self. In a healthy bond, both people still have their own identity, limits, and needs. Codependency is when those get lost in service of the other person.
It also isn’t a clinical diagnosis, and it isn’t a fixed label for who someone is. It describes a pattern that can change, not a flaw baked into a person.

Boundaries are the limits that codependency tends to erode and that recovery works to rebuild. People pleasing often overlaps, since both involve putting others first at a cost to yourself. Anxious attachment can fuel the fear of stepping back that keeps the pattern going.
When it helps to get support
If your sense of worth depends on being needed, or if caring for others has crowded out your own needs to the point of exhaustion or resentment, working with a mental health professional can help. Therapy is a good place to rebuild boundaries and a separate sense of self. Support groups and self-help resources can help too, especially when the pattern is tied to a loved one’s addiction or illness.
When this word matters
It matters when self-worth depends on being needed and caretaking crowds out a person's own needs, because the pattern can lead to exhaustion and resentment. The loss of a separate self, not generosity itself, is the issue.
