In short

Every guide on Psychology.com in one place: mental health conditions, types of therapy, how to start and pay for therapy, and the life situations people bring to counseling. Each article is written by a mental health professional, reviewed before publishing, and dated.

By the numbers: Mental Health Statistics 2026, 60+ sourced figures.

How the library is organized

The guides fall into four sections. Conditions covers what a diagnosis means, how it shows up and what treats it. Therapies and approaches explains how each kind of therapy works and what the evidence says. The starting-therapy guides cover the practical side: deciding, choosing a professional, paying for it, and knowing whether it is working. Life and relationships covers the situations people bring to counseling that are not disorders at all.

If you are new to all of this, Getting Started With Therapy walks through every step in one place. If you would rather check your symptoms first, the tests are free and use validated questionnaires where one exists.

Conditions: anxiety, mood and stress

Common questions

How are these guides written and checked?

Each guide is written by a mental health professional and reviewed by a licensed clinician before it is published. The author, reviewer, publication date and last update are shown at the top of every article. Sources are cited in the text. Our editorial policy and review methodology describe the process.

Is this medical advice?

No. The guides are educational. They can help you understand what you are experiencing and decide what to do next, but they cannot diagnose you or replace an assessment by a professional who knows your history. If something you read fits, the next step is a conversation with a licensed clinician.

How do I find the right guide if I do not know the name of what I have?

Start with the conditions library, which is grouped by how symptoms relate, or take a broad screening such as the mental health assessment. The "is it this or that" guides below were written for the case where two things seem to fit at once.

What if I need help right now?

If you are in crisis or thinking about suicide, call or text 988 in the United States to reach the Suicide and Crisis Lifeline, available around the clock. If you are in immediate danger, call 911. Psychology.com is not an emergency service.

Reading about it is a start. Talking to someone is the next step.
