10 Mental Health Disorders That Can Be Severe

1. Schizophrenia can involve hallucinations, delusions, disorganized thinking, and difficulties with motivation or daily life, although experiences and treatment responses vary. 2. Bipolar I disorder can involve manic episodes that disrupt judgment, sleep, relationships, or safety, as well as depressive episodes that may carry suicide risk.

3. Major depressive disorder can become severe when persistent low mood, loss of interest, exhaustion, or suicidal thoughts make it difficult to work, eat, or care for yourself. 4. Anorexia nervosa can cause serious medical complications from inadequate nutrition and may require coordinated medical and mental health treatment, regardless of a person’s appearance.

5. Post-traumatic stress disorder (PTSD) can severely disrupt sleep, relationships, and your sense of safety through symptoms such as intrusive memories, avoidance, and heightened alertness. 6. Obsessive-compulsive disorder (OCD) can become disabling when intrusive thoughts and repetitive behaviors consume substantial time or interfere with everyday activities.

7. Borderline personality disorder can involve intense emotional distress, relationship difficulties, impulsivity, and self-harm risk, but effective treatment can help. 8. Panic disorder can seriously limit daily life when recurring panic attacks and fear of further attacks lead you to avoid places or activities.

9. Substance use disorder can be severe when continued alcohol or drug use causes major harm, impaired control, or dangerous withdrawal; some withdrawal symptoms require medical supervision. 10. Bulimia nervosa can cause serious medical complications through recurrent binge eating and compensatory behaviors, and you deserve help even if those behaviors are not visible to others.

If symptoms are interfering with your life, a qualified health professional can help you assess your needs and discuss treatment. If you or someone else is in immediate danger, call emergency services; in the United States, you can also call or text 988 for suicide and crisis support.
