Resources — Understanding Depression
Welcome to the resources page for Understanding Depression — Beyond Sadness. Everything below is curated to go alongside the guide.
If You Are in Crisis
If you are having thoughts of suicide, self-harm, or feel you may not be safe, please reach out for help right now.
- Call or text 988 — Suicide & Crisis Lifeline (U.S.) — free, confidential, 24/7
- Text HOME to 741741 — Crisis Text Line — free, confidential, 24/7
- Go to your nearest emergency room if you feel you may act on those thoughts
You are not alone. Depression lies. The thoughts that tell you no one cares, that you're a burden, that nothing will help — those are symptoms of the illness, not facts about your life. Reach out.
