Mood Changes
When It’s an Emergency

A shift in mood can come from stress, depression, anxiety, substances, medications — or a medical problem. Most mood changes don’t need an ER. But if safety is a concern, it’s an emergency.

Call 911 or go to the ER immediately if you or your loved one:

  • Talks about suicide, wanting to die, or feels unable to stay safe

  • Has intent to self-harm, has already self-harmed, or is making preparations (giving things away, saying goodbye, researching ways to die)

  • Threatens or intends to harm someone else

  • Is seeing/hearing things that aren’t there, extremely paranoid, severely disorganized, or not in touch with reality (possible psychosis)

  • Has extreme agitation, panic, or mood swings that are unsafe, violent, or out of control

  • Is confused, not acting like themselves, or the mood change follows a head injury, overdose, or sudden medical symptoms

If there’s immediate danger, call 911. If there’s a mental health or substance-use crisis and you need urgent support, you can also call/text 988 (24/7).

24/7 Emergency Care in Houston (Post Oak / Galleria)

Walk in anytime for adult and pediatric ER care, with on-site CT, X-ray, ultrasound, and labs for fast answers.

Get same-week help (doctor, therapist, or urgent evaluation) if mood changes:

  • Last 2+ weeks with persistent sadness, anxiety, or loss of interest in daily life

  • Include major sleep/appetite changes, frequent panic, or you can’t function at work/school/home

  • Come with increased alcohol/drug use or stopping substances and feeling worse

  • Are new/worsening in teens, or include risky behavior, rage, or withdrawal from everyone

  • Happen during pregnancy or postpartum (especially with severe anxiety, intrusive thoughts, or inability to sleep)

If you’re unsure where to start, 988 can help you decide what to do next and connect you to local support.


When mood changes usually do not require an ER

Most mood shifts — even painful ones — are best handled through primary care and mental health care (therapy, medication management, and supportive follow-up). The ER isn’t the best place for long-term treatment — it’s for immediate safety and urgent medical stabilization.


When mood changes can signal a medical problem

Sometimes “mood” symptoms are driven by the body (medication side effects, intoxication/withdrawal, infection, dehydration, sleep deprivation, hormonal or metabolic problems, head injury). If the change is sudden, severe, or very out of character, it’s reasonable to seek urgent evaluation.


What Post Oak ER can do (Houston)

  • Perform a rapid safety assessment and medical evaluation

  • Check vital signs and screen for medical contributors (when clinically appropriate)

If you feel unsafe right now: call 911 or text/call 988.
