Virtual ER · 24/7 Emergency Telemedicine & Virtual Urgent Care

24/7 Online Anxiety, Acute Stress, Insomnia & SSRI Refill Care.

What to tell us about your symptoms

Changes in mood, sleep, concentration or anxiety can be reasons to seek support. A brief description on a website is not a diagnosis.

What the video visit can help with

Bring up what has changed, how long it has been happening and how it affects daily life. Mention current treatment and medicines. Our physicians and nurse practitioners can discuss the concern and whether a different or ongoing service is needed.

When an examination or testing may be needed

A video conversation is not a promise of a specialist psychiatric evaluation, ongoing therapy or a particular diagnosis. Ask which services are available and whether the clinician’s role fits what you are seeking.

Discussing treatment

Care may involve discussing next steps, the need for continuing support or medication questions within the clinician’s scope. A visit does not mean a particular medicine will be prescribed.

When support cannot wait

For emotional distress or thoughts of suicide, call or text 988 for crisis support. If there is immediate danger, an attempt in progress or a life-threatening emergency, call 911. Do not wait for routine online care.

Before your visit

Use a private space where you feel able to speak. A short note about your main concern can help, but you are welcome to start with the words you have.

Questions about this care

Is this a substitute for ongoing therapy?

No. Confirm the available service with the team. A visit can help discuss next steps, but continuing therapy or specialist care may require a separate provider.

Your next step

Let’s talk about getting you care.

Start with a video visit. Your clinician can help you understand what can be addressed online and what needs care in person.
